[QUOTE="Justin@VMP, post: 14576134, member: 18468"] On my GT500, I did not drive it for many months, it had 3/4 tank of gas in it. It started up and idled fine on old/bad gas, but as soon as I started to roll into it (and generate boost) it pinged, I let out, drove it easy, and push some fresh gas in after the tank got low. I think gas that is 2-4wks old is just fine. Filling up too often and getting whatever was left over in the hose (if its one hose for 87/89/93) is a bad thing too, I always recommend putting a full tank in. IMO the MAF pegging thing was more about cobras being tuned too aggressively back in what I call the dark ages of tuning (10-12yrs ago). If you want to make a case for that I will tell you the 07-09 GT500s will peg the MAF in STOCK form, which is why we never put a pulley on them without first putting a larger CAI on (which increases maf range). That being said, most of the aftermarket CAIs and intakes out there don't peg easily, and if you do, the GT500 motor does not go lean all that quickly. [/QUOTE]
