Well worth the $$$$$$

Reviewed By Rick C (Altoona, PA) Reviewed for a 2007 GMC Sierra —2/7/2017 3:04 AM

I installed this on my 07 sierra. Simple as can be. I've noticed more power and acceleration. Transmission seems to shift smoother. Great investment.

I noticed the engine opens up now when I want it to. Before the response wasn't there. But it wasn't easy figuring out the shifting configurations. I had to research some forums but there's not much shared about it. I paid $275. Great deal
