The truck is not a DD, Mainly weekend wheeling the kids around and pulling a 24' inclosed trailer and Racecar (6000 -6500 lbs.), and running hotrod parts around town.
I am having a hard Time deciding on the proper tunes for my truck.I was thinking 65 Tow, 80 DD, Stock, anti theft, lope idle(any down side to this?) and Smoke (if it will do anything with stock injectors)

Do these sound about right for my truck. Please advise if anything needs to be less ar more aggresive.


Thanks Jason

Jason,

For a 97 with stock injectors, I would shy away from the smoke show only because the 80P will give you about all the stock injectors are capable of. There isn't much sense in paying $25 for a tune that won't be any different than the 80P. The lope idle is neat if you're into that thing, but I'm afraid the novelty of it will wear off quickly, especially with an automatic transmission. Holding the brakes against a surging engine isn't much fun for long.

With a 3" downpipe, there is very little worry of excessive EGT with stock injectors as long as you keep the engine in a decent RPM range while towing. Lugging will create a lot of smoke and high EGT.
