I just had the APR chip installed. I defintaly like it but have a few concerns I hope someone might be about to help out with. I only get full boost if I start the gear at a certain RPM. Some times if i start out in first slowly then hammer it once im going like ten it only gives me 5 psi of boost. It does that in all the gears. Another thing is if im going less than 65mph in 5th and give it full throttle it bounces from 10 psi 10 about 15 psi. Is any of this normal, or should i be able to get boost in all gears regardless of the rpm range I choose to go full throttle in? When the boost does kick in it definatly moves though. any help would be appreiciated. Thanks

20psi on a 1bar chip? that doesnt sound normal.

20psi spike's way too high

That what the gauge shows. Runs like a squirrel on fire.

No driveability problems and smooth as glass.
