Reviewed By James W (Rupert, ID) Reviewed for a 2003 GMC Sierra —3/10/2009 4:36 AM

It took longer to install do to the fact I had a cold air intake. No whitsle and 1 mpg gain. Also have a programmer and I have not been able to figure out results yet.JW in Idaho

Install was fairly simple. Can't tell a huge difference but there is one there especially with the jet throttle body and spectre air intake.

Reviewed By Joseph N (CLINTON, ME) Reviewed for a 2011 GMC Sierra —9/21/2016 8:17 PM

As far as I can tell, it does what it's meant to. I put this on before I put on my Spectre cold air intake to test it and noticed an immediate throttle difference, definitely added some power. And it hasn't messed with my mass air flow sensor. Don't buy this to save gas though, I haven't noticed much of a difference. Wasn't too hard to install either, just make sure you have a socket set and a pair of vice grips at least and you'll be fine.
