I just put one on my LT1 w/ a FIPK CAI and love it, I can tell the car runs ALOT smoother and has better throttle response---

 

The big difference you feel if from the CAI. You also must have not noticed what Madwolf said. It is his buisness tuning cars PCM's. Take his word for it. You could have spent less money having your pcm tuned, kept your stock maf and gotten better results. More for you $$$

 

Yeah but people prefer to listen to advertizing and then when KNOWLEDGABLE folks try to help they they dig their heels in rather than admit they made a mistake buying a $300 paperwight.

 

They suck and can be hard to tune.

I needed a new MAF anyway, so I decided to get the Granatelli for the same price as the stock one. I have heard of gains of 5rwhp from mostly stock cars and 2-3rwhp from a worked motor from dyno tests. Even if all I get is better throttle response thats cool with me. I know they can be hard to tune, but thats not my problem, lol....its the guy's I am paying $150 to tune it---
