Question about boost fluctuating.
Question about boost fluctuating. Need a little help guys. My boost is fluctuating quite a bit. Ive got an 08 C6 M6 with a procharger on it(p1sc, 6rib) and Z06 exhaust. I am having issues with the boost as you can see by the graph. The exhaust is not up to par but it should not cause this issue. The P1 with a 4.25 pulley only made 7.5-8Psi. I swapped it for a 4.0 and only picked up approx .75 psi. We thought it would pick up more than that. The belt is not contacting itself during a pull but if I really get aggresive with shifting it will, causing belt slip. The WG seems to be working properly... Can those of you with experience give me some input on what the problem might be and how to fix it? Here is the graph.
