Traction controls completely off and have all new boost Solenoids and everything so not sure if I should rock with v10 a little longer or switch back to v7 where everything seems to be fine.

Turbos also wine like crazy when I'm in the lower rpm's have actually had mutable people tell me it sounds like I'm supercharged, still pushin strong though

Haha another one whining lol,

Slight overboosting is normal, should smooth out after a few runs.

Can't say for sure but It looks like Ken used the throttle closures on V10 maps to smooth out WGDC, out of the OTS maps they seem to pull the strongest, only exception being V5 E40

Saying that, according to my tuner need to run at least 1 or 2, 3rd logs for adaptations to set. Immediately 3rd gear logging after a flash doesn't give best results.

Welcome to the whiners club

Mine also whines loudly at low rpm with no side effects, and yes, it sounds a bit like supercharger sounds.

May I ask how old are your turbos?

[Saif2018]

I speed read that as Winners

Whiners club lol

[E90nick53]

Car has 87k miles on it and turbos have never been touched as to my knowledge. I got the car at 70k and did all maintenance plus fbo right when I got it. Did the inlets about 6k miles ago and checked both exhaust and intake compressor blades and no visible damage and no shaft play. Been whining for about 10k miles with no other symptoms of turbos going bad.

Good to know, when I first saw the throttle closing even with traction off I thought there was maybe a problem. But I'll rock with it for a little longer, car seems to like it and feels pretty smooth

If they're massive closures, they're an issue but if it's a few %s, I wouldn't worry. Personally I still think i'd like the V7 maps the most.

As we all know though, custom is the way

My STFTs on OTS maps always were around +/- 15% at the top end, not a big deal but one of the best improvements i've seen with a custom is even on the top end i'm usually at no more than +/- 6%

Ok thanks !

Nice you checked your turbos, no shaft play or visible damage to blades, new inlets (sometimes whine comes from one of them cracked/popped off) and still whining.

What else could make them whine ? turbo bearings I imagine, anything else?

It's normal for the turbos to whine after tuning. The tune is closing the wastegates earlier than stock which causes the whine. The sound will be amplified by DPs and DCIs.

Enjoy the normal turbo noises. I think it sounds freaking awesome and I only have DPs with stock airbox.

Yes, turbos/air sounds are more pronounced when tuned.

But we are talking about this kind of whine, low rpm (between 1500-2300rpm) whine/police siren when turbo starts to spool :

On mine, it's not a sound that developped after flashing a tune, it's a whine that developped over the months running 18-20 psi for extended period, I doubt it's normal. It developped very fast on two new mitsubishis on mine, a few months only, and getting worse these last weeks.

With old turbos, I ran Stage 2+ without a whine for over 2 years, but I was only running V7 during that time, so less PSI than on V9 or V10.

It's definitely not normal. Had zero whine until turbos were on a custom tune pushing 20psi.

That's not correct. I never had any whine on my stock turbos until turbos were boosting near 20psi and regular ripping as mentioned.

Both my n54s started to whine after tuning. One has 5000 miles and running stage 2, very loud whine. The other has 52000 miles and I literally just flashed stage 1 on Sunday and then noticed the whine. It did not do this stock.

Mine never whined at stage 1 or 1+ and I'm over 130k miles on them, only started whining after reaching 19-20psi on custom tune.

Ask around and see how many RB Billet or 1/2 whining, I haven't found any.

Stock turbos just whine when pushed, wouldn't call it normal.

Did you have catless DPs? I'm sure that make the whine more audible.

I can imagine they would, but no I have the stock downpipes on now.

The whine is only audible at low rpm from around 1k to 2.5k

As soon as the turbos start building boost, its no longer audible.

Even switching to OTS maps with lower boost doesn't reduce the whine, which leads me to believe some part of the turbo is damaged.

Just wanted to add my take on V10 after driving on it for months. Needless to say I have gone back to V7... my favourite.
(Stage2+ 93 map with 94 fuel)

V10 feels more slightly powerful than v7 but that was the only positive for me. A few things I noticed:
V10 does not pair well with XHP IMO. I believe they have made some changes to the shifts mine were so harsh they would lunge the car forward. I enjoy driving around in M-mode and V10 felt way too aggressive and harsh for this. WOT shifts were great and F -N fast but normal and low throttle was terrible. This was my main complaint. My car is a daily and this just bugged me a lot. I'm sure this could of been fixed with adjusting all my xhp stage 3 settings but I didn't want to do so.
Another issue is lean codes for both banks would get tripped during normal highway cruising. If this was one bank or the other I would be looking at hardware. Since it's both it most likely points to the tune.

I have flashed back to V7 and I love it. Shifts are smoother and the car is much nicer to drive as a daily . I agree V10 probably makes more power and felt more aggressive but that was not worth the trade off for the harsh shifts. The lean codes have not returned on V7 either.

Some of this might be old news but I figured I would post my thoughts since I have spent a lot of time on both.
Thanks

I have had a totally different experience than above, I was also a V7 faithful, both 8 and 9 where not good but I really like v10, on my car it is just a better v7. I have a 30k mile 2008 and v10 runs super well on it and works perfectly for me with xhp stage 3, super smooth shifts in sport, fast and firm but smooth and no lean codes afr is spot on, running new coils and plugs but original injectors still.

No virtual dyno and what ifs. Hot night and spark plugs weren't the best, I switched them out after that night and felt slightly better so I know it's in the 540WHP on a hot day. Fbo stock coils and stock hpfp. Oh and this is not on V10, I realized after I posted, this is on V5 E40. I think this is the best OTS tune that you can get before going custom. over 500whp and trq

[darkrom]

On my 135 the v10 maps surge. Take your foot out of the gas and it's like instant jerking and what feels like something wrong with the throttle. While accelerating it is super jerky. This is with no m mode throttle and no changes to anything throttle related. Flash back to v9 and the car runs great. I tried 10 a few times and unfortunately this issue always comes back and isn't present for my particular car on v9

[roadkillrob]

I am still liking V10 on my car, but I did experience one weird issue when I needed to get inspected, I flashed map zero and the car was virtually undriveable, it felt like some type of valet mode basically barely would accelerate, felt like it had like 100 hp, no lights or issues just literally so slow I couldn't drive the car. Flashed it back to stock (long write) and all good did my inspection and flashed V10 back on it and back to normal. So if anyone else tries map zero, curious to see if it acts the same or more like stock?

Still getting constant surging on v10 and even v9 now…

I'm at the point where I'd buy a custom tune but I'm starting to wonder if it's an issue with the MHD app not the tunes. Id hate to pay for a custom tune to have the same issues. I noticed one of the mhd+ apps had "throttle fixes" as a description, but at this point I can't even drive my car on mhd the partial throttle and throttle release surges are so bad.
