Be nice to dyno your truck to get the base and then add their MAF sensor to see if it really works like they say. How could they resist the test? Wonder......

" Oxnard, CA - Granatelli Motor Sports, Inc., the world's # 1 best selling performance brand, is proud to introduce the installation of a state-of-the-art chassis dyno at their 39,000 square foot Oxnard headquarters. The dyno, a 1800 hp all wheel drive unit from Mustang Dynamometer, uses Mustangs constantly evolving data acquisition software . According to J.R. Granatelli, president of Granatelli Motor Sports, "we have the first and only customer friendly all wheel drive chassis dyno in Southern California. And, it's open to the public as well as the media.

LATER!

I wouldn't pay for MAF until after the dyno was done. I had bought a $350 one as present for the camaro for Pat and the only thing it was good for was a cup holder -:t

One of the reasons I do not buy mods for either the car or the truck without consulting him first:cool:

Well here is the story

Yeah, I'm not his biggest fan. They guaranteed a 10HP gain, and showed a dyno sheet with a 25rwhp gain on the same model and year as my car. I told him face-to-face "I expect 5rwhp gain from this after tuning, can I return it if it doesn't?" and he said "Certainly, but your gains will be much higher!". After 3 attempts, no MAF they could supply would match the HP of the OEM MAF. After showing them the dynos ($300 worth of dynos) suddenly the warranty was void. "Your car is different!" Uh, 2000 LS1 Camaro with stock engine just like the dyno on their box. On closer examination, the dyno curve was for different year Camaro with the LT1 engine, no matter what they say. Curves on the two engines are ALOT different, and did not come close to any LS1 curve I've ever seen. When asked to produce a copy of the dyno, the said they would send me one. That was 4 years ago, still no sheet.

I'm not the only owner who fell for it. And typically on car dyno days I attend, if a car runs like crap, I'll look under the hood and if I see a GMAF on it, we swap it, and the power picks back up.

LOL:D So, how did it hold up as a cup holder???

Pat is the man !!!!
