Scared me for a minute. Even so, that's up to about .75 of an AFR you could get back -- think where you could spend .75 AFR

Haha, well I was at 105% IDC on my 6.39 run last week. When I finish my cam swap im going to try 70psi base pressure which will make them 139.5lb/hr to see if that helps.

So that's 1367 bhp (using the .78 BSFC which isn't correct at that IDC, right?). How much boost?

Retuning for your meth would help a bit too.

It ranged from 99-105 if you want to get picky, lambda from .78 to .8 with meth on top. Around 20psi

I found the .78 while not using meth, so im actually using more fuel than the IDC alone would tell you.

Yeah, but you are also using more IDC now so the BSFC would be higher than .78 too, yeah?
