Nice that is like 340-350 Tq at 3000rpm, i bet that gets the big CC movin.... Your setup is exactly what i want when i by a CrewCab.

Is that a 114 or 112 lsa on the cam? I bet you would gain a little more with alot higher lift cam but on the same duration, probably a little flater Tq curve as well..

31 rwhp from heads is great!

Are you thinking about going bigger on the cam?

I'm liking the TR230.

its a tr224 on a 112. i thought about a custom cam but i dont think it would be enough of a gain for the expense. esp with as good as it runs now. it is my daily driver and won't see much track time. not to mention this stall isn't big enough. plus iat's were 105 at the beginning of the log and 99 at the end.

31rwhp must have felt like a huge SOTP gain

3rd gear pull was night and day difference. 2nd now feels better after leaning it out a bit. air/fuel was 11.8 on the first pull. the trip home was fun.

Yep, you got a badass ride, no 2 ways around it. Do you have EFI live? I'd love to see a log of your runs.
