mass air question

[tiffo60]

i put the 90mm mass air and my predator tuned the truck for it but i am going to have to take the pulley and programmer off the truck to get the transmission warranteed and am wondering since i dont have the stock 80mm to put back on it will my truck run with the 90mm and not tuned for it?

No, it won't run correctly.You will have a rough idle and throttle response won't be there.

There's a default tune in the predator for a 90mm MAF on a 99-00 truck without a pulley that should work.

The only problem will be if they flash over the computer and you have that tune in there.

See if it will run that way, if not someone will let you borrow an 80mm. It shold be rich if anything.:tu:
