Superchips

[dmerk1978]

installed the flashpaq today and it's a pretty good enhancement from what i had before, easy to install easy everything, just have 1 question. when i gun i it in performance mode i hear a slight rattle(not overwhelming) before it kicks over to another gear, does anyone get this same noise?


my set up is as follows:

2007 YUKON DENALI 6.2
K & N COLD AIR INTAKE
MAGNAFLOW DENALI ESCALADE VERSION
SUPERCHIPS/FLASHPAQ

The noise you may be hearing is an "engine ping" when you hear that you need to take your foot off the gas and not gun it. Your pistons may overheat and your engine may die . I run a Hypertech Programmer and it did the same thing I called the Tech's at Hypertech and they suggested that I should run higher Octane gas. I currently use premium 91 octane and programmed it for regular gas (87 octane). That seems to help out. Hope this helps.

I was also told that if you have any other mods ( air intake, tb spacer, etc...) its more likley that it will happen.

You definitely have to use at least 91 octane with the Superchips in Perf. mode.
