After an efilive dyno tune can I still use my predator to make small changes? Shift changes, small fuel and spark changes at the track? Thanks

 

Yes, but be sure to do so using the factory hp tune, not the diablo tune.

 

OK, that would be the modify performance section. The tune that came with Diablo never worked well once I started with headers and so forth but I was able to reduce fuel ,add spark, shift points and get good results with the predator. Thanks for the reply.
