03 5.3l Silverado 20-100+

Old set up

Stock cam, Full bolt on, 3k stall, 4.10's, Wheatley tune.

Cut-out open in vid

Tune was pretty much dead on. Most recent video before the tranny blew up.

Once speedo hits 110 the speed sensor starts to mess up =/

I got a hypertech tuner in my 5.3 its pretty fast but im looking for a better tune. i gave 370 dollars for my hypertech is there a cheaper way to tune it at a shop?

[Unkn0wn2003]

No sorry he doesn't tune fords

[Unkn0wn2003]

They are both good tuners. I think they are both equal
