Hey guys, I just got a used Granatelli MAF and the guy didnt know if it was tuned for a Cold Air or not. I noticed there are two different logos on the MAFS, and didnt know if that meant how old they were or if they were tuned. One just says GMS in cursive, and one has a race car with fire out the back. Is the race car one the cai tuned one or just the newer one? The #'s on the upc on the bottom are 89873781259 and its engraved on the sensor part 2615A
0304 THANKS FOR YOUR HELP!!!

ps I tried emailing Granatelli from their site and it comes up as an ERROR---

 

Do a search here on Granatelli, then put it on ebay.

 

I honestly wouldnt worry about it. I asked a lot of questions once i bought mine a long time ago since i was putting a cai on too. All it does is help if you have turbulent air to keep the sensor from being thrown off. Mine hasnt screwed up at all i dont think, and i really dont think mine is cai tuned.

 

Hey Tainted, I think I am going to like it too. I dont have a part number, lol....the instructions are for 9 different part numbers, lol and doesnt say the part number for this one. I think the fire breathing car is the CAI one, I am almost positive--- ---

 

The way you can see a gain with the Granatelli has beeen covered over and over as has why you can get even more for less by tuning the car. I am aware of one guy who actually dyno testred and tuned for each a stock and a Granatelli back to back on the same dyno and he saw something like 2-3hp on a over 300rwhp car, WELL within a dynos error range and even if true HP that is $100+ per HP.
