Cobb Accessport Map Selection

Just wondering which map you guys think I should be running. Doesn't seem there's really an exact fit for the mods I've got.

Injen CAI, SU Testpipe, Medieval turbopipe, BOV, TMIC, colder plugs... think that's about it. Always run 93

stage2+SR 93 oct

my guess

I would suggest getting ATR and getting a tune based on your mods. Running anything different than what the map notes say can result in serious issues. I ran a Forge BPV with Stage 2+ SF and it pushed 22psi of boost! I ended up taking it off and going back to the stock BPV.

I did the exact same thing...unfortuantley it was a while before ATR and I got rid of the 1st gen forge...Stock BPV does just fine for me.

I would be careful about running stage 2 if you don't have an upgraded fuel pump and it's cold where you live. I was running out of fuel with stage 1 around 4500-5500 rpm's here in Michigan. Fuel pressure was dropping into the 700-800 psi range.

I saw this happen once so I don't drive it hard when its really cold. Around 32 degrees I get 1400-1600psi so I am happy for now.

QFT. Zoom zoom boom. I've seen it happen! Maybe I was even driving....

interesting... sounds like stage 1's the safer route. but what the turboback exhaust option? I only have a testpipe... does that suffice or should I just leave it be?

You have to experiment. I have heard people get buy on stage 2 with a testpipe. Technically the map asks for a catted downpipe which would be ideal.

Try a stage 2 map and data log a few pulls. See if you are getting knock or overboosting. make sure you have a good, stable AFR and you should be fine. If you are suffering from the above, try a stage 1 map.

Unfortunately, its a test and review process to find a good map unless you want to get a custom map or make one yourself.
