From what I have read changing to higher compression Pistons and RV cams won't work with engines controlled by a computer Because the computer cannot compensate enough to give the engine a correct fuel to air ratio. Seems like a different fuel air ratio wouldn't be needed after a compression bump of a point or two. Anyone had success or read of someone having success bumping the compression on this engine with different pistons?

 

Found something about raising the compression. http://www.sporttruck.com/techarticl...r/viewall.html
