Thanks. There's a few spots I need to clean up the MAF table a little but ran out of time.
I'm very fortunate to have a dyno at work. There are all sorts of things I want to test given, I have the time and the money to buy some parts.![Nod](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_nod.gif)
We are a dealer for BTR so I am wanting to try out a couple of his camshafts and see what the differences are.

Thanks I appreciate it. The car used to be H/C/I. I had a Comp Cam failure and the TEA 5.3 1.5 heads that I bought off the forum that were "rebuilt" had a bunch of valve guides wore out and it smoked like a freight train on decel.
Due to finances at the time I put the stock heads/cam/intake back on. I already had the cometic's so I used them.

I had it at the track after I put it back to "stock" and it was trapping slower than a bone stock car. I put it on the dyno and found out my MAF was bad and went to about 1.08 Lamda 15:1 AFR above 4000rpm . I replaced the MAF and just now had a chance to put it back on the rollers.
I will say that the Frost mail order tune that I got a couple years ago (when I put the car back to "stock") was damn impressive (MAF table). My MAF/Lambda error was with in 5%
above 4500rpm.
His tune was commanding PE was about .82 Lambda which is about 11.7 AFR, which I completely understand being rich and staying safe.
I leaned it out to .88 Lambda, about 12.7 AFR and made a few small timing changes and picked up 14hp and 9 ft lbs. This was back to back runs. I'm sure there is a little more power to be had but not much.
The low end of the MAF transfer table needs some work. I didn't have time to look at the VE.

Well at least you've now established the shortblock is healthy and a good test mule.
Just curious where's your shop located? I grew up in Evansville but haven't lived there for 6yrs now.

Got it. I thought maybe you'd been there awhile as there was a shop on that stretch that always had some sort of muscle car or two for sale sitting out front. Good to know there's finally a shop with a dyno in the Evansville area that has LSX expertise. Best of luck on your endeavor!

Nothing crazy, customer wanting to crack 650 or so to the wheel.
