Default Re: This Just In... All 2008's must run PREMIUM!

Bumping HP is just adding fuel/air then adjusting timing. If you are running what factory calls for then take it to dealer and have it checked something is wrong. It could even be the knock sensor. You may need a spark plug colder or hotter. There are so many variables to a knock it takes someone with software etc. to check it out. You could play with a handheld, experiment taking notes save allot of money and figure it out.

Tuning is note hard just requires some study up front on how the new stuff works. I use to just ear tune back in the muscle car days. I miss it. Run Accel distributor stuff etc. Figure fuel/air ratio on a printed table based on carb, heads, cam, and just figure your way. Once it was all done the final timing was done by ear at about 2000/2500 rpm by ear no timing light. I could put my 68 Mustang 289HP 3/4 race cam, roller rocker/lifters, and tunnel ram then time it perfectly on the money. Next it was pink slip time.
