Cobb stage 2 +, questions

Hey guys, just about to install my fimic to hit stage 2 plus on cobb, there are very few reviews out there regarding this subject nothing that I would consider well reviewed.

Does anyone have this ?
How long have you had it for ?

Is stage 2+ a bit too aggressive ?

I have a full stock body and rime, but full bolt ons, coils and XI

Any input appreciated.

Cheers.

Yes people have used it. It's not that aggressive in terms of a protune. Do yourself a favor if you're going to be FBO, get a protune. One map for pump and the other with E85. You'll see the huge gains.

Yes protune is my next step, I am just about install the fimic...

When I say too aggressive , I am putting it in regards to the stock oil cooler and sway bars and all the other stock components.

I drive hard, last thing I want to do is have to replace all of these within a years time.

The stock turbo is pretty small, I havent heard of may issues and it seems to be able to run boost upto18 psi without premature failure however I could be wrong hence wanted to get some input.

I don't understand how the tune/FMIC would have anything to do with the suspension in the car? All you are going to be doing is picking up a little HP, probably like 15-20whp.

Youre definitely overthinking it. I doubt you drive that hard in relation to the audience youre talking to.

Stage 2 is when you have ... at least a chargepipe and a downpipe and preferably a catback exhaust:
http://www.cobbtuning.com/maps/bmw-n...0b-stage-2-map

However, the off the shelf (OTS) Cobb tunes for N55 are not very good. Get a protune/etune from PTF or Wedge.

You should get a CP if you don't have one and also the GFB DV+ to hold boost

I'm currently using Stage 2+ FMIC AGGRESSIVE and the best time I've ran was 13.2 in an E90. I'm also FBO, and have tried this with a full tank of 93, and then a 70/30 mix of E85.

When I go from a dead stop and launch, I'm roughly around that 18psi mark. Oddly enough, when I pass someone on the highway, I can get up to around 21.8psi.

If anyone has had a protune done with our similar setups, I would be very interested to see numbers and logs. I really want a solid answer on whether or not it's safe to squeeze more power out, or if I should continue saving for Pure Stage 2. It would be cool to have a tune now just to help pass time.

I am kinda in the same boat, with this fimic the turbo is going to be seeing some heavy duty work cycles , hence I dont want to end up with a damaged turbo , I am just at 50K miles... However it seems people on the forum drive more aggressively than I do and there have been very few complaints on this turbo so I am not worrying too much about it

I am getting a pro tune as the next step, its 250$ ish, look forward to that. If someone has a protune done or has a JB4 with cobb backend flash, please let advise

I'm stage 2 Aggressive on the Cobb AP3 and I have 4" DPs, CP and GFB DVs and 5" inch step FMIC and it is a night a day difference from Stg 1 and Stg 2 without these parts.

I've pulled up at 19 and up to 21 psi easily and I believe I could do more if I get the Protune, I'll more than likely do the PPK and then the Protune and see what I hit up after some datalogging.
Good luck with your set up, you'll enjoy it but get yourself some DPs.

What was your mph and your 60" time? 13.2 seems high considering your mods... I would think 12.6-12.9 would be the range??

Probabably a RWD manual....or maybe RWD auto. All the ET would be lost at the 60'...
