ENGINE PROBLEM WHEN BOOSTING
hi there, i just want to see if anyone can help me out with my problem.. Ok here we go, its a 92 nissan 240sx with red top sr20det, mods are FMIC, 3" hks exhaust, s14 t28 turbo and a greddy profect b boost controller. when i drive it with boost off the car drives fine and strong, but when i boost the car anywhere from 8 psi to 14psi the engine runs funny, its like the rpms are going up and down like it has a leak somewhere. its like the turbo is giving power but then it looses it. but it rung really good when the boost controller is off. and it only shows that on stock boost its only 6psi and a s14 t28 turbo boosts at 8psi. HELP ME OUT PLS
