The big tires will make a difference but there is more going on. You have a bunch of good guys on the job though, so I am sure with patience you'll find the weak link and get-er-done! A stack with the smarty and a rail cap would be the next best bet I think.

 

How high did your EGTs get? Sounds scary!

 

I made 468/923 uncorrected on a dynojet with nothing more than a smarty, 5" exhaust, and DD clutch, and im running 37's as well.

 

Don't blame the 37's...I have dynoed 575 without the CP3 or the sticks.

Tune Tune Tune...

 

Thanks guys for the feedback, like rye says give it sometime.

And I will for sure get on another dyno to compare.
