since i put a .50 trim t3/t4 on the car i was getting boost at 1800-2000 rpm and full boost by 3600-4000 rpm depending on which gear i was in. now in low gears im getting boost at 2200 rpm and full boost around 4500-5000 rpm and i cant figure out why. i thought it might be a boost leak but i cant find one. if anyone has any suggestions it would really help me out.

 

check your bov to see if it's closed all the way, also check you wg. If either of those have a leak it will cause you to build boost later....check your charge pipe connections also

 

ill do that thanks, i have played with the bov it seems to be in good order, but im almost postive its a boost leak cuz im only hitting about .38 bar when i should be hitting .45 bar, so im gonna go and check everything

 

they all seem fine, any other ideas

 

check your compression.

 

i dont know how to do that, the car seems to run really good, just a lot of lag

 

ttt

 

my car idles around -450 bar now, any clues, i figure its just a vacuum leak but i cant find it. i replaced most of the lines, but it didnt help at all. any clues?
