Just picked up an 08 vette with A&A V3 with 3.4 pulley, btr3, fore fuel, id1000, headers, yank 3400, meth,dsx flex fuel. The previous owner ran best of 9.67 at 143 mph so the car seems good on the top end.
However I took the car out for a spin today and the drivability seems pretty crappy as it bogs between shifts. i'd consider my self a beginner/amateur at tuning but im looking for some opinions on where to start here.
I haven't had a chance to log it since the weather hasn't been the best in Chicago and I haven't installed my wide band yet. This car was tuned by a well know tuner.
things I've noticed:
- timing seems low compared to my old cts-v on e85
- injector data seems off(flow rate vs pressure is all the same number?)
- maf curve has some bumps and is not the smoothest
- o2 rich vs lean voltage seems odd
- power enrich looks pretty lean
- im still learning tranmissions but any input is appreciated
Tune file attached. corvette tune.hpt
Any help would be greatly appreciated.
