Today, i was driving to work and noticed i was hitting 5 psi and 10 psi with proper throttle position. But for some reason when I hit 5 psi and then hit 10 psi it seems as no increased acceleration. As a matter of fact it feels N/A but my boost gauge read 0-10 psi. I have had the problem of the TCA not opening and having to take the car out of gear and put it back into gear to get full boost. Accleration seems extremely slow that compared to honda or something maybe overly exaggerating. Also, sometimes it feels faster with only 5 psi then 10 psi, I have no idea where to start diagnosing the problem. I should have a DP by the end of the week so im not sure if that would cure the problem, I highly doubt it.

 

dp may be the ticket.. pre cat being pluged. how many miles? how fast/smooth does it build boost?

 

Occasionally its instant build like it jumps to 10psi when hitting then sometimes when it goes into the 5psi mode ( I swear i can compare my car to a woman in so many ways) it likes to build up slow almost like big lag.

 

Anyone??
