Wanted to get some feedback from people who have all GMPP parts on their car. Looking for some HP numbers for GMPP Stage 2, manifold, and cat-back and some 1/4 mile times if possible. Looking to see what HP I could expect?

 

I have- Touring exhaust/manifold/stage2. Also had the XTC down pipe and i cut the STOCK air box and put a k&n on it. So its pretty close to all gmpp.

Other mods were rear SSC springs and DC strut tower brace (i dont think these do jack ****) but some people might think so.

Stock tires/30psi. Car had like 3500 miles on it at the time.

I went 13.7@103 with a 2.2 60-ft

Without the xtc i went 14.4@100 with a 2.4 that was the only run i got in that time because the 2nd run i broke the driverside axle.

I have GMPP Stage 2 and cat back sport, runs very good.

I get 242hp and 219tq on a Dynojet with stock airbox on.
