What ever-.I don't care if anyone does not think this is true,Have charts to show HP and TRQ.This truck is very strong .I haved raced 03 ss beat him by 4L and also 04 dodge H 3 L and pulling. As for gas Mileage,fulled to the lid-60miles thur town fill to the lid again 16.1254.MPG, 60 miles on HYW 62MPH filled to the lid again 21.268 .LBRS

 

Decent numbers.......Looks like 260 rwhp and 290 Torque (when you discount those crazy shift spikes)

The only real dyno is the track...or street in your case....

I have had really good luck with repeatable numbers on Dynojets....Great for checking mod differences...

260/290 is more like it. My '02 Denali was 281/310, so you're about 20hp/20tq shy of what I hit with just a Flowmeister.

So in essence, that could be just different dyno numbers. I'd delete your first post with the ridiculous numbers you posted. Those are just spikes. I'm shocked the dyno owner/runner wouldn't tell you that. To let you leave thinking those are real numbers... well, sounds like he's trying to make a fool out of you. I'd let him have it. Also, I wonder why your graph is so messed up?

I'm also wondering about these trucks you beat. As SS by 4 car lengths? Uhmmm, yeah, I don't think so.

 

Weedo is right, you can't read the spikes, read the top of the curve between them,
nice gains anyway.

Ahhhh, shift spikes! That explains everything. Sorry about the in the other thread.

 

Nice gain either way...I only wish you could gain 100hp/105tq from bolting on an air intake, mufflers and a little programming.
