Hi guys I have a pretty much a stock 95 GSR other than obx 4-2-1 headers. I Hve come into a large sum of $ and want to start to tune my GSR. My plans is to do a N/A tune becuase that is how I tuned my old LS and my other car my 96 Toyota Celica. If you guys could give me some pointers that would help me alot. I am looking for about 250-275 whp and a nice sounding machine.
