I tested the FVV8 and 9 chips, and was happy with both. The new Delta chip is supposed to be the best offering from Diablo so far, but I have yet to test one. A little different driving style is in order after the chip install, as WOT will take you to your rev limiter. It isn't a chip problem, it's the TPS being tossed out of the circuit. I can't explain it, just trust me.
I have the chip and the EFP cam, and pulling 80 mph in L2 is easy. Fun, fun, fun.....
AND I still get 34 miles per gallon, no matter how hard I drive her. Take that ZETEC boyz....
