Top end? Mine ran to 150mph on the dyno in 3rd gear. It shut it down because it said "Max Tire Speed exceeded."

Re: Need a few mods for 5.3 Yukon...
.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
Ok, how did up to 13hp turn into a 20+hp gain?
Gains in the peak numbers will only be about 2, 3 or 4hp. This product helps power in the low - mid RPM range.
Info from VaraRam -
In Truck applications we have seen gains of up to 22+ ft/lbs of tire-shredding torque throughout the power curve where you can use it! As tested in a 2004 Silverado 5.3 V8. In LS1 car applications, gains of up to 13 rear wheel HP have been seen (03 C5 Corvette).
The "tire-shredding torque" statement may be a little optimistic. I have this in one of my 8.1s and actually did see better throttle response and a gas mileage improvement over the last 3 tanks.
VaraRam can be reached at 1-866-507-2648 if anyone wants to discount this with them.
As for top speed, I've seen a little over 130 in my 6800 lb brick

What are the current dyno gains people are seeing on a basically stock 5.3 (with intake)?

Re: Need a few mods for 5.3 Yukon...
I just ordered a UPD - am I correct in understanding that the VR t/b insert will not work with these?
Also, is there an additional 'cold air' mod I can do to the UPD intake for more gains?

I've have the burb up to a GPS verified 135mph, she's got more in her but The suspension need to be tightened up to run comfortably at these speeds.
