Dyno day today. Truck made 552.4rwhp and 575.7rwtq on a Mustang dyno. In the next few weeks I hope to get some track times, I'm looking for sub 11.50's.

Nice gain! Did you tune it with meth?

Yes, it actually made 566rwhp peak on just pump gas but the area across the curve was up and down like crazy. It made a ton more average power with the meth and slightly lower peak power. It's still a pretty safe tune. I'm very impressed as I'm still on the stock fuel system!

Stock fuel pump? MAF or SD tune?

Made some passes. 2 best ones were 11.969@115.04 and 11.93@114.78. Everything was slower than my previous best, my 60' by a tenth, my ET by 2 tenths and 2 mph yet I'm making 66rwhp more. It was pretty hot out today. I'll get there eventually.
