For HP? I made 319 at just under 17psi. I had an MSD ign. and a grounding issue so at top end it was blowing out spark and cutting out pretty hard. It has a lot more in it I just am having someone else tune it.
Bob Kurgan. He's really big in the mustang world. It was a really restricted Time limit when he did the tune. And I ran an SPA manifold. And now with my TS one I'm sure m numbers have went up some. Since the tune I have made a few changes that made quite a difference to the feel. So ill strap it down soon and get updated numbers
Handling isn't bad since I'm sitting on Eibach coilovers. But grip without my slicks lacks. It will spin through 3rd and breaking the wheels loose at the top of 3rd gear is a little freaky. Its a little better with the slicks on but still spins 1st and 2nd.
