SHORT NOTICE-Sound Performance is hosting a dyno day today and it's free.
Hey guys, on Wednesday May 27th Jason the owner of ProEFI will be at our shop all day and night showing off his products for the Z/G. We will have cars on the dyno throughout the day with Jason answering questions and going over the tuning process. After 6PM we will continue with the tech seminar as well as open the dyno for anyone that wants to make a few runs COMPLETELY FREE OF CHARGE!!!
244 to the wheels, but I only got one run while others had two. I wanted him to do another one cause he manually upshifted, but then when he pinned it in 4th it also downshifted on its own and he let off right there. I have an srt intake(worthless) and apexi ws2 cat back. If srt's claims were true about 30+hp and 40+tq then I think my numbers would be different.
My car did the same on the Dyno. It wont hold gear. I bet your #'s are better then that. Time to boost that bad boy I think someone on here may be selling there GS and have some parts readily for sale soon
