Installed Fast 90/Ls2 TB today and.... It seems it caused my tune to richen up? Does that make sense? I had the stock Ls6 and 75mm TB before now with the 90/90 setup Im richer everywhere especially WOT....Went from like 12.8 at WOT to 12.2 and 11s in mid range? Im still running the MAF and fuel trims. I guess a VE retune is in order....

I Dunno It Didnt Make ***** Worth Of Difference In My A\f .. Have You Tried Clearing Your Trims .. Im Not Saying Somethng Is Wrong But Even When I Sent My Pcm Back To Tsp For A Retune They Did Nothing To Compensate For The Extra Air Allotted By The Fast's Better Flow And Im Running A Similar A\f Before And After

Interesting.... Im wondering if the Ls2 throttle body opens differently and that is what is causing my tune change. Since both TBs are drive by wire I wonder if that could cause it????
