hey i just recently put on my 3.4 intense pulley and when i punch it, it will hit 10 psi on the gauge but it feels like somethings wrong like it will run real rough and make a noise like its dying down then it will be fine..... any answers would be great.

What belt are you running, what octane, do you have any way of scannign the car? Did you put cooler plugs in the car, t-stat, fwi/cai?

What other mods have ya done?
Intake?
Exhaust?
Cooler Plugs?
Good tune-up ?

It could be the knock sensors pulling timing on ya.

You could cruise to 06082 on Saturday and we could scan it up and check'r out. You look to be about a 2 hour drive.

As the guys above mentioned.. we need to know what else you did for other mods.

yea i got the intense FWI, different plugs, gatorback belt

the problem feels like the car is taking in all the boost and then lagging out like its resisting to go more....

Sounds like you have knock retard. We need to get a scan.
