Got the files and better graphs today, just for fun heres the new motor baseline vs my original setup basiclly 100kmile motor (red) vs 227kmile motor (blue). Much better to start with.





Heres the baseline pull (blue) vs the vtc turned off ( red) made about an 8hp increase up top. This new motor is running a little rich for some reason, dont know if the wideband from the dyno was good though, got to check a few things on the engine.





This is a tune with timing and fuel made the best increases down low almost 40lbft of tq below 4000rpm.
