I few weeks ago, I installed my new coil pack granatelli, new granatelli wires, NGK Iridium Spark Plugs colder 180 t stat and a aem sri also a catch can. Since then I have not gotten on the car yet, so today I was on the high way and when I floor it the boost gauge does not go past 10 psi, but before the install the car would easily go past 10psi and go to 12. I pulled off a ramp and was at a stop light when it turned green, I shifted from 1st to 2nd then I floored it and again it wouldn't go past 10. Also when I am at a stop my exhaust sounds like it is making a small back firing noise. Any ideas of what I can do?
I'm thinking what he said...most likely everyone will tell you the same thing...first thing you need to do is a boost leak test.
Ok. I will do that. I am pretty sure it can be the intake since the guy I bought it off of had the 2.5-3' piece cut a bit and I put it on like that I might need to put some RTV sealant on that if possile to fix it.
Honestly if your car was only boosting 12 lbs to begin with...I think you definitely have a boost leak. Stock an SRT-4' should be spiking around 14 lbs of boost.
