I have questions on computer chips or power programers whichever.... i want to buy a power chip that would best comply with what i have now and will have in the future... as of now i have stealth air box, maf, borla, and headers are comming and so is a ram air, and any sites on those things would be helpful too .... so anyone that can help or give advice i'm open for it... thanx

 

custom tuning is the way to go.. do not buy any off the shelf programmer

 

I was warned by a Chevy mechanic not to raise the rev limiter unless you do some internal work to the motor. He told me that the "rods will look a little more U shaped than they should". Obviously that is an exaggeration, but I think I will take his word for it. He told me that he has had to fix quite a few LS1's that had a programmer raise the limiter.

 

Dave, is there an issue with the "Diablo sport Predator" ?? I was planning on a purchase soon, so if you have any info please share it.

 

I ran my rev limiter to 6500 w/o any problem.

 

let me tell ya, the only thing in an LS1 going to break from rpm is going to be a valvespring problem or bent pushrod. the lower end handles it fine. ed wright seems to be a popular choice.

 

Obviously that Chevy mechanic knows little about LS1's. I've had my rev limiter set at 6600 since I got my heads and cam. Comp 918 springs with stock pushrods. I have yet to have a problem with bending pushrods or with the bottom end. When I was stock I was shifting at 6200, still no problems. These LS1's love to breathe on the top end.

 

the only one's i've found with pushrod problems are over-revved LS1's with the stock valve springs. this is usually from a accidental downshift instead of upshift under ful throttle (obviously manual trans cars) causing it to go well past the rev limiter.
