Boost Problems
Just got my FMIC and boost gauge on and my car wont boost over 8psi.. i think it goes go 8-6-8 but i didn't drive it around enough to get the exact numbers.. i did a little searching but didn't find any real help.. heres a picture of the new setup.

My mods are; pettit intakes, pettit downpipe, pettit pulley kit, catback, greddy fmic, greddy elbow, greddy type s bov, 8lb flywheel, and a pfc but its not on right now.. Any help to why my car is boosting wrong is appreciated.. thx- Eric |
Probably just a boost leak from something that loosened up during the install. How does the coupler look on the bottom of the stock plastic cross-over pipe? That can be a problem.
Nice to see someone else with f'd up filters on their pettit intake. |
So, you just got the boost gauge and FMIC done at the same time?
If so, your boost problem probably existed before your FMIC install. I assume you are still running the main cat, how many miles on it? |
The boost problem definitely was there before the install.. and yes i got the fmic and gauge done at the same time.
I am still running the main cat and theres probably 85k miles on it? When i bring my car back in to do the non-seq conversion i will be putting a pettit midpipe on it. |

Thats good news.. when i go wot it almost feels restricted kind of like its having a hard time.. its hard to explain.. hopefully the new midpipe will fix this problem and the boost problem... Thx Mahjik you always are really helpfull - Eric

ditch the cat, get a dog

Check and verify that you still have the factory vac lines on the waste gate and precontroller. 8-6-8 is very close to 7-x-7 which is the boost pattern w/o the factory pills in those lines.
