Finally got it tuned. I'm happy with it.
 

Lingenfelter GT12 cam .614 .621 Duration @ 0.050": 227 235 (LSA)115
Home Ported 243 heads with Manley Race Flow 2.00/1.55 valves
Home Ported Dorman LS2 intake with a 92mm WARR throttle body
42lb GTP imjectors
TSP 1-7/8 long tubes with ORY and a Dynomax 3" catback

First pull was only 365 which I was bummed out on but I did figure he'd get more out of it and also told me it's a pretty tight dyno. All pulls were on a unlocked converter. I was honestly happy as hell as soon as I saw 400
2nd 394
3rd 407
4th 417
5th 419
6th 422
And the 7th...

Looks good

is it me or the AFR curve is very lean? was the AFR logged or unplugged?

Oops, I should've noted that this was the extra pull he did with the cutout open, and the sensor was still in the tailpipe.

Looks like good results with nice curves for hp & tq,. Thumbs up!

I'm impressed with the home ported heads & intake.
If I tried porting heads they would end up being recycled into beer cans.

LOL I think any attempt at porting by me would look like a cave carved out of rock... with sledgehammers!

lol at the porting comments! I can't wait to get it to the track now and see what it'll do....or how many runs the rear diff will hold up to :)

Ask the dyno guys for a plot with RPM instead of MPH

Yeah, I noticed that after I left the place. Never thought they used MPH I would've like to see RPM instead

You should be able to run 7.6-7.7 na now maybe a five if your lucky.

I think the 3.23 is gonna hurt me but I don't wanna change it since the diff is gonna grenade sooner or later.
