To properly max a turbo, you must run open DP

yea, i don't really know. the tuner is good. we tuned at 11.8 a/fs on the dyno and this was due to me still running a cat. the tuner says when you run a cat, you can go a bit leaner cause the cat messes with the reads. .

i'll check for a boost leak, i really don't think i have one, but i'll check.

Well I just know that on my lex/550 setup with a 60-1 trim CT, I can get boost spikes well beyond 20psi without FC. Getting the turbo to hold 20psi is a different story.

could a dying AFM cause FC. i'm pretty sure my AFM is on it's last leg.

when i was drag racing last night, the car would die when i hit the brakes after the run and if it rains the car runs liike shit..lately the idle has been getting worse too. my sensor does have 180,000 miles on it
