Yeah numbers are in the ballpark. Torque being the exception. Thats why I tried locking the TC the one pull. All the pulls were with the meth. I didn't add any timing at the shop. I have 22* total advance at WOT in the tune now with the METH. Absolutley no sign of KR so may be more in it. But hell if the dyno numbers are correct what's the point of adding more if it doesn't make any more power? My first pulls the engine was heat soaked and the PCM pulled timing due to IAT sensor. I'm going to quit calling it Intake air temp, its more blower temp. PCM pulled spark down to 17*. I pulled it again later in the day after it had cooled off. PCM didn't pull any timing for IAT's and it ran 21.5* advance during these pulls.

Yeah overall it was a good day. Just left with a lot of questions. This does not make sense to me.

Yeah, most of the guys with the driveshaft problem (myself included) have longer aluminum driveshafts. I haven't heard of any 2 piece shafts. Chime in if any of you have.

You dyno 200 more ponies than I do. How many puzzled mustangs do leave on the road in a week? Congrates on good numbers through that long drivetrain.

As many as will test it usually.

Either way... nice numbers. I've run my truck to 6250 RPM's in third gear before (rev limiter) on the highway with 3.73's a couple of times and it really wasn't shaking or vibrating in any way. I think you'd be safe, but I'm not an engineer.
