Need a few mods for 5.3 Yukon...
We just picked up a 2003 Yukon, it's got the5.3 and 3.73's, but we just want to personalize it a 'bit'.
Namely, an intake, programmer, and JL box for the time being. Which intakes are people liking now, FIPK, Volant, etc.?
What about programmers, the HPP3, Predator, Superchips?
My main concern is lifting the top speed ban, how fast will these things run on the top end anyway?

I would say Westers Tuning, UPD intake, X pipe into 2 spintech or magnaflow mufflers. Plus the wheels Blown is talking about. Its what I want to do anyway. Stereo wise, a JL stealth box like you mentioned would be nice. Have fun!

Cool, I'll wait on the wheels until we burn these new tires down
I didn't see the UPD intake on tbyrne's website (which is the only one I had time to check), is that the one showing the most gains on the dyno?
I did see a Velocity Stack, 22rwtq gain? Snake oil or are people really seeing this?

Man you came to the right place in order to get the best bang for the buck.As you can see in the above post i just did an 03 tahoe 4x4,it is bone stock with stock tire size.Westers tune is the best thing you can do for the first mod.Call Lyndon and
have him do yours exactly like he did mine.Then do the UPD,then do a set of long tube headers.I am not big on catbacks because any aftermarket will cause a drone that may or may not drive you nuts.I am surprised Tom is willing to endorse that snake oil velocity stack,The claim was up to 20+ HP gain? Ya on WTF vehical,i would like to know exactly which vehical they got this on and would they guarrenty 10HP gain on that same vehical.You know they wont.

Thanks for the suggestions, what will these things run on the top end with the Wester's tuning and 3.73's?
