I know it's pretty much impossible, but could someone take my dynosheet and do a "best guess line" of what my stock tune dyno #s would be? For some reason the first base run cut off around 5500 and did not record on the sheet, making it look like I gained 57 max hp just from a tune lol I have contacted z1 and their computer that had all the saved runs crashed, so no way to get it back. But someone who sees alot of this stuff may be able to help as to what an average car might do. Mine is an 07 Z and I had Stillen gen 3 intakes with CNT resonated test pipes, and a HKS rep exhaust with the resonators cut out and magnaflow resonated x pipe welded in place. I am just curious and would like to be able to show the real gains at car shows, etc

 

Looking at your graph, I would say 278whp
