Ok so after installing a testpipe and stage 2....I am overboosting to the point of fuel cutoff...sometimes...most of the time it will peak at about 26-27 but once in a while in first or second it will go much higher...like 30-31...any suggestions? I took off the testpipe and uninstalled the cobb b/c I got fluids chanced at Mitsu...but plan on putting them back on to try maybe putting my stop bov on since that is supposed to start leaking at like 25.....thanks for any help guys

 

maybe try the lower wastegate map that cobb provides?

what is the temperature like there?

 

Sounds like we may need to make some changes to the wastegate tables for your car. Can you tell me the exact map file you are using?

ive done both regular stage 1 and regular and LWG stage 2

Stage1+SF 93 v400
Stage2+SF 93 v400
Stage2+SF 93 LWG v400

 

personally that was the only regret i had with my evo x was buying an AP. imho.

I should have got a pro tune.

 

My I ask why???

 

you can get a protune with the AP... in fact "protune" is cobb terminology getting a personalized tune...
