I'd like to hear opinions on long term reliability using Cobb in a daily driver with occasional long trips. Is there any reason to think that Cobb will shorten the expected life of the vehicle?

[MagicJ]

Also would like to know if there's an expert Cobb ship in the Atlanta area.

I would say if you tune your car with anything it will effect the longevity...

These big single turbo cars are not meant to be drag cars. Their times are not impressive for what they are unless they have a shot of nitrous down low, supra's included. What is impressive is blowing the doors off of ferrari's and lambo's at the airstrip or highway. Probably only a handful of people buying these kits will ever post a slip.

All of these products have a place in the market and appeal to different people for different reasons. I love my cobb and plan on going no further than a stage 2 with mine. The car will be fast enough for me. I can't wait for ATR to hit the streets!

With the current mix of owners you may be right, but I could easily see a bunch of new people being drawn in by the AWD option once big power is available. If it catches on most of those people will be posting slips.

What max boost should I be seeing with V3 stage 1 agressive. Last night from a dig I saw 16.2, this morning i'm only seeing 15.5. Does the boost adjust with climate conditions?

Yes, cooler temps will lower the boost required.

Hmm I have an automatic transmission and I run stage1 aggressive linear throttle, version 3.X.
Are you saying its not good for my car? Should I change immediately to stock throttle map?

I think he is talking about alternate throttle, not linear. There is Stock, Linear, Alternate 1 and Alternate 2.

^ BlackBB6 is right, you're fine.

This concerns me because at 5000ft I am already seeing 15psi on v4 DRIVE map peak in ~75 deg temps. Does that mean at 90+ I could see 16psi just to reach the same target? Does the target not adjust based on conditions and always remains the same and it just knows I need to make 350HP so no matter what, I need to get there (and then because it ran more boost...my turbos go 'pop'!)! Just curious, as maybe I am mis understanding how it works otherwise.

I just opened my AccesPORT Manager and it says "AccessPORT Manager version 2.0.2.3 is available... Release notes: Unable to load release notes... Do you want to update now?" so I click "Yes" and it starts downloading the update, but then it says "Downloading AccessPORT Manager update: Not available" and the program crashes. Anyone else have this problem?

And? Did you fix it somehow?

no still messing with it now, gonna restart comp and try again. thinking the problem may be on cobb's end, maybe server problems..

Yeah I think that's what it is... I even uninstalled the program and re-installed it off the Cobb website and it's still not updating correctly.

any updates on the ETA of an n55 accessport?

Not that it makes a huge difference, but are you using a mac or windows? Was gonna update my AP, but I don't want to my AP to crash and make it useless.

You're essentially right about how the tune operates. The tune is looking to hit the load targets regardless of conditions. HOWEVER, that doesn't mean that that it's full power or bust. There are caps in place to prevent over working the turbos.

Also, it's important to keep in mind how turbochargers work. Basically, all the turbo does is spin. The wastegate on the hot side opens or closes allowing more or less exhaust energy to spin the impeller faster or slower. As the impeller spins the compressor spins.
As engine speed increases the compresser speed must increase in order to maintain the same "boost" in the intake manifold. So, high boost in the low mid RPM range is A LOT easier on the turbos than it is in the high RPM range.

Here's COBB Website @ 1:04 AM EST. Servers crashed, killing the AP Updates, Map Downloads & COBB Blog. Hopefully it'll be up in the next couple of days, was looking forward to installing my new parts & using the Stage 2 Maps

crap
Here i was hoping to flash my car today, but ofc unreqogniced ROM
and the rom dump site on cobbs site isnt working

Thanks for the response. I thought it was about right. I do realize that 15psi at 3.5k is less stress on the turbo then 15psi at 6000. My concern was just as temps/elevation changes and taking spirited driving trips to the mtns that I would wind up overworking the turbos and lead to a premature death. I wish (hope) in further updates they can address this further perhaps for us high altitude owners, since, in theory, our turbos are already spinning harder to make boost in stock form.

Out of curiosity, any idea on the caps? I'm sure it's same for sea level or 10,000 feet, which I know, not many people drive up that high, but the fun CO roads are up there so it would be nice to know. Or I suppose I just have to flash to stock map when I go up and back again when I come down.
