Re: ENGINE BREAKING UP AND MISSING BETWEEN 5000-6000 RPM
I know you mentioned new plugs..... was that when the SC was installed a few months ago??? The first thing I can think of is to check the plugs, even though they are a few months old. You may be getting some detonation and have possibly damaged a spark plug(s). If you find that you have detonation I would suggest hooking up with a reputable tuner right away and have him add fuel or pull timing on your program. Right along with the first theory is that you may be starving for fuel up top, I would hook up a pressure gauge and check this..... if your starving for fuel you are definately detonating which can or has already taken its toll in terms of engine damage.
Good Luck in getting to the root of the problem..... keep us posted on what happens.
