440rwhp/390rwtq after a Ed Wright tune. Not bad, eh?

He's a slow poke. Waiting for him to see this and post his graph. They are corrected numbers.

Sorry bout the camera pic. I don't have a scanner. I tried to get Ed to send me the runfiles so I could open up WinPEP and do a screenshot but he didn't have a way to do that. Anyways, here is the graph he gave me.

Ed said these are the best numbers he has seen from Lloyd's heads.

I had Bret's LE2 grind originally. I am not going to answer any q's as to why I no longer run that cam but I will say I am much happier with the GM847.

Very nice numbers - I would expect an 847 to peak after ~6400 on a 355 though!

Must be a blast to drive, and cant wait for some track times!

Thanks everyone Gotta give some credit to Aaron (MeanGreen97Z) I think he was probably ready to come up here and kick my *** if I didn't get this thing done. He was my go-to guy when I needed to vent when **** didn't go so well.
