wierd boost numbers
OK i finally fixed some of my boost leaks...i can actually feel the turbo now...but my gauge is reading 10 psi in 1st gear then drops as my rpms rise...the psi moves up about 1 lb in each gear...so 2nd would be 11...3rd 12....4th 13 and so on...why is this??? could there be another boost leak or is it my MBC's fault??? Thanks

Re: wierd boost numbers
first, put your car in your sig along with any mods...
the boost dropping in higher rpms is because the turbo is maxed out at anything above 5500rpms (if you're on the T25). don't ever check to see what psi you're constantly running in first gear because first gear is way too short and redlines too quickly to get a decent reading...get in third gear, around 3000 rpms and smash it, then watch the boost gauge. the boost should stay around the same psi in all gears, i don't think you really have a problem. what kind of MBC do you have?
