I put a Diablo on an 03 today and then went for a spin. The truck has small aftermarket injectors in it as well. EGT's were surprisingly low but didn't want to cool down fast. It really surprised me with the power for it being an 03 with no other mods except the small injectors.

My Diablo has been ordered. I've heard sooo much its time to try one.

 

With my HTB2 turbo my temps don't go above 1100 degrees even on the performance tune. I guess that turbo is really working well with this stack because with the old Quad box I could easily get to 14-1500 degrees on a hard pull. I towed 10-11,000lb up to Michigan a couple days ago and even through the mountains in Pennsylvania my temps only reached 1200 degrees tops. I think I have found the perfect combo once I get me a better clutch.......

Phil, you are on a mission to try every box out there aren't you?!?!?!

 

You bet!!!!! I'm learning alot about how these trucks work the more and more I play with them!

 

a guy on the diablo site dynoed his 03 with the predator only and got 430.5hp and he only had a intake.he actually dynoed lower with the puck stack,that was the factory extreme tune not tthe custom rkl extreme,hes gonna dyno the custom tune soon and let us know,i think the predator for the 03-04s is a great tuner.

 

when i put the puck on 90 its alot stronger. i dont run the stacker tunes but i do stack the puck when i want to go fast. big d/f with puck on, i can tell you that.

-the tst tows alot better i am finding out though (more tq). but it rattles like a son of a gun.

-diablo is alot smoother and easier on parts

 

i love my predator, and i dont know whats up with some guys seeing high egts cause i never see about 1250 on xtreme setting...and i think iam goin to try stacking the Quad race box without timming and see how it acts...
