H1 Alpha top speed

[Huck BB62]

Hi H1 folks. I've got a raging debate on what the top speed of the H1 Alpha is. I know it's a silly argument, it's just for bench racing's sake. Anyone here remove the limiter and found out?

I dought you will found someone who has due to the risk of warrenty and heat issue.

I have an 06 alpha. 80 is about all I have seen so far. I agree with the other response concerning the warrenty.

I understand, the Dmax is an expensive critter. I'm still surprised that noone's chipped and did the aftermarket exhaust thing on their H1. Tons and TONS of people are doing it to the trucks. But again, being a Dmax owner, I completely believe that it's fine stock, so I never bothered. Personally, I believe that the H1 could do about 120 with the program change.

Plenty of people have done this change. I know of two H1 owners making over 600 hp in their duramax rigs. Lots of people that do those mods buy them through the dealer and dont post online. The parts dept at my local dealer is about to put a stage III computer in one of his customer's Alpha's.
