i was at a dyno day, and it was 2 pulls for $45

first pull i spun the tires on the dyno, and they counted that as a pull (whatever, i feel ripped off and wont return)

after i see the dyno sheet, i know something is wrong

PEAK horsepower is at 4600 rpms, then slightly drops off until 6500rpms? I am thinking it has to be valve float.

would you guys agree?

Valve float would be a sharp ppwer drop off. What were your numbers before? Remember that a mustang dyno can give drastically different results than a dynojet.

I've never heard a single good thing about mustang muscle. Im not sure where you live but there is another dyno in ruma, il called Larrys electric. His specialty is lt1 and ls1 wiring and computer systems. His only downside is he doesn't have a wideband o2. But if you decide to give him a try I could meet you there and let you use mine.

these numbers were on 7lbs, and E85... I wouldn't think that I'd be blowing spark out either.

I have a wideband in the car, I just can't log with it.... it's carberated.

Are you running a good quality spark plug wire? Before I bought my msd wires i had some junk Taylor wires that would start to "bleed" at higher rpms.

Pop your hood tonight in the dark and look for the light show. On my camaro I noticed the most arcing where the wires cross over behind the power steering pump. There was also some arcing around the steel frame of the coil.

Your definitely right as I remember having a set of brand new Taylor wires years ago and they arched at night.

I pulled them right off!!
