Mine ran 112.5mph with 363/392, so you should be close. I can tell you dyno dynamics do normally read lower than a Mustang dyno. They call them a heart breaker for a reason.
Put my car on the dyno today to get an idea of where I was at. This is a safe DD tune, Adam says it has a lot more in it when I want to step up my game. Sorry it's a little hard to read. Thanks Adam for the awesome tune.
The bad info is also coming from you. You write stories not posts, doing so people will think you know what you are talking about. Unless you go back and edit your incorrect post the info you give is exactly what you yourself just talked about. It's wrong. I have more stuff just sitting in...
Plan on the swap taking several hours, you have to drop the craddle, the carrier will not come out unless you drop the craddle 4-5", brakes, shocks, axles all have to be removed, I was at it for 10 hours but 4 or so hours was figuring out the yoke problem and I did other stuff at the same time...
I have done the swap and I can assure you the yokes are in fact different. Look at the pic you posted of the "actual yoke" you see that centering ring on the outter edge that the DL slips into. Well that ring is about 0.180 smaller on the EBM yoke (if memory serves me right). The bolt circle on...
Bought my PP GT complete drop out with 1800 miles on it for $600 shipped out if a crashed GT. Worth every penny. You will need to swap the yokes if you do the swap on a MT car.
If 4.10's would have been available when I did mine it would have had 4.10's and not 3.73's. My car is my DD it is not a weekend cruizer. The 3.73's are way better then the 3.55's as a DD. Sure I know this goes against normal thinking with a turbo car, but it works for me.
I ran 13.2 @ 108 on stock tires and E30, little more refining on the tune and DR's I went 12.6 @ 112.5 You just need to go do it. If you run better then 13.4 you'll be doing good in summer weather. 13.2 with good weather conditions.
