I have an audi a4 complete S4 swap with unitonic stage 2 ecu...thats why the guy who has the swap before me told me....

my problem is when I floor it from 1st gear to the 3rd gear I reach from 12 to 15 psi, and in the 4th gear reach 14-15 psi, and 5th-6th gear reach 18 psi but drop to 16psi

And also when I floor it in 4th-5ft or 6th gear I feel like I have no power

I not sur if its really a stage 2 chip...but its sure im not stock.... I have k&n air filter, bov upgrade, downpipe, cat back , front mount intercooler

Sorry for my english im from quebec, canada....Im a french guy

 

first off do a boost test. you migh just have a few minor boost leaks.

heres a cheap diy:

no boost leak

 

are you throwing any check engine light codes? are you running upgraded diverter valves or did you switch to blow off valves?

 

finally no missfire code only an intermittend O2 sensor (first of the passenger side), 1 of the ECT defect... with the vagcom I read the request and log boost....depend witch gear is engage, from 16 psi to 20 psi...
