With the high price of gas itspricy to run 91 octainperformance mode on the superchips programmer. I own a 2007 Chevy classic model 4.8, a friend of mine said no matter whattype of gasyou run the truck will auto correct and will never ping. Can you run 91 performance mode with 82 octain? Will this damage the motor?

 

Anyone?

 

Give it a little time, someone will know. Just refresh on occasion. Sorry I have no idea.

 

Jester, I have also have the Superchip Flaspaq and I advise against running 87 with the 91octance performance setting. It states in the owners manual and the website that you must run 91 or higher with the 91 setting. I'm having a difficult time finding any hardcore evidence to support my theory, but I will call Superchips on Monday and find out the truth. If it were me, I would not do it.

 

Thanks again chevy lover!

Their is a huge difference in horse power and gas mileage running 91 performance mode. Now that I have felt the difference their is no way I can go back! [:@]

 

No problem brother, glad I could help again! You are right, there is a significant difference in power between the 87 and 91 setting. When I go on long trips or such, I will install the 87 program because of gas prices. Other than trips, it always stays on 91 octane setting.

Have you checked out the acquisition package online? It is a program that will give you 0-60 times, 1/4 mile ET, and all sorts of other cool stuff like air/fuel ratio, transmission tempature, etc... It is a free download, so check it out. I had some bad luck trying to download it. After I attempted to download it I received a error message and my flaspaq literally froze up. I contacted Superchips and they were very helpful. I mailed them the flashpaq, which they paid for shipping, and I am now just waiting to get it back. If you ever have any questions that I can't answer, just call Superchips. They are a good company and will do anything to help you. You don't find that much anymore.

 

I think you do that only so you can beat up on defenseless stock 07 Town & Country's

 

Well, I had to pay you back some how for beating my *** in your Camaro!

 

Hey - it was a close race (mycar vs your bad mother ****in truck!)...

 

Thanks bro, but it was hardly close (15 lengths)! Maybe when I install that new jet engine in my truck I'll be able to keep up with you.
