No huge gains, but Greg at Racers Edge Tuning upped the ramp rate on the fuel injection so it hits harder/faster when you give it the beans and leaned her out a tad. Also upped the line pressure on the 6-speed Auto for a little quicker/harder shifts. Oh, almost forgot he increased fuel cut off from 6000rpm to 6300rpm. He didn't go too lean with the tune, cause he knows I'll be 'road racing/autox'ing' it and knows I'll have the car under load in the higher RPMs. But on the dyno it wasn't hitting any knock sensors... which is nice.

Overall made the car realllly nice to drive, very crisp and responsive. My LSx Guru friend says that should put me over 400hp crank, but that 6-speed is soaking it all up, what a greedy bitch of a trans! haha

Guys there are pretty legit, very knowledgeable for a buncha 'Mustang' guys. haha... some pretty sick Mustangs/Shelby's/Saleens in the shop getting tweaked on.

mmm great numbers. I'm running an l76 in my bird with nothing done but a cam swap, and I didn't get to dyno the engine before the cam, so it's nice to know what a near-factory configuration is capable of.

any chance of pics/vids/cookies/complimentary moist towelettes?

Sorry, no videos... :(

I was sent over there last minute by a friend, so I just went with what I had in my pockets, didn't have time to swing by the house and grab a camera.

But I do have a print out of the last dyno run, I'll try and get that scanned for your viewing pleasure.
