here are a couple 3rd gear street pulls, same stretch of road on 93 pump gas. This is my own tune. based on my 93 pump tune but i now have the following mods:
Fa20club.com 4-1 long tube (currently with cat, soon to be without)
nameless over / front with cat and helmhotz
custom ft86speedfactory varex catback
Varex is in the open position for both pulls. This tune is essentially my last pump gas tune with cam timing and fuel map revisions for the headers. If you look closely you can see that i am trying to dial out some overlap where the leanspot shows up at 3200 rpm.. also the injection volume will show why i think it is overlap causing the lean spot... as it is consistent with load.
