turbo help

[JimmyJ]

hey whats up, i have a 95 talon tsi with a injen intake, hks cat back, 550's, 255 fuel pump, and a evo 111 16g with an AFC11. I have a manual boost controller also. I cant seem to get above 10 pounds of boost and when i hit the gas the car like stutters and jerks and at high rpm's it is just not smooth. It hesitates and and seems like im not getting any fuel or whatever it is. its pretty bad and my car is running like crap. If you know why it is doing this let me know
thanks

If you're not getting more than 10psi your boost controller is most likely hooked up wrong. Which one do you have and how do you have it hooked up? The stuttering and hesitation is most likely your plugs and wires, replace them with NGK stuff.

2 options like he said...replace the plugs first that caused my car to stutter in the higher gears...as far as the mbc bein hooked wrong...theres 2 vac lines goin to your mbc...one comin off the j pipe and one coming off the bottom of the turbo....try flippin them around and than give it a shot make sure you turn your mbc back down if you turned it up already to see if that would help. dont want to be hitting 20 psi on accident other than that if yuor running the stock SMIC check your piping or take off the heat shield and check for exhaust leaks that would cause your car to run like crap as well if you have a big enough boost leak
