I was wondering if anybody has the Superchip and did you think it was worth it. Also how does it work and do you need to change to a different gasoline grade. I was looking in to getting one, but will it hurt the motor in the long run and did you really feel a difference in performance.
oh my god yes it is worth it, my truck is so much faster now, the shifts are firm and it tows a hell of a lot better now . . . . no you dont have to change fuel grades if you dont want to, it gives you the choice of either 87 mode or performance mode, which requires 91 octane. i also noticed a gas mileage improvement of at least a couple of miles to the gallon..

yep , 'pretty much the same story, except I'm starting to think twice about the Tranny reprogramming after reading this forum, I may get a new valve body for that firmer shift .
Can you not have the tranny shift harder. One thing that I have heard was the tranny are not the greatist of trannys for reliability. I like the performance gains but am affraid of the damage from hard shifting to the tranny.
the 4r100 may have had some weak links. but it sure has a lot of parts out to beef it up if needed. parts for the 5r110w are just starting to trinkle out from the after market.
don't worry so much. the 4r still when stock can take a big beating before it fails.
The ones with multiple settings would be best so you don't have to run premium all the time. My experience with the Superchip was the tranny shifted way too hard at even the lowest setting. If a tuner offered fuel and timing curves and possibly tranny shift points without changing line pressure it would be great.
Alot of my friends have suggested to me the hypertech programmer since they are easy to use and they have had good results with on thier chevys. I just drove my one friends Tahoe. I drove it before and now after the hypertech install. It was responsive, but not aggressive. Seemed much better than stock to me. He raves about better mileage ect. I wouldn't know about that, but atleast it isn't too much of a slug anymore.
When I ran my Superchips, I loved it. The throttle response and the overall engine performance was significant. I always ran the performance tune which required 91-93 octane fuel. I left the tranny in the default Superchips setting. It was relatively mild. At normal acceleration it was hardley noticable. The firmness of the shifts increased with the more throttle added. There was one time that I was tired of the guy tailgating me on the highwas doing 70 so I put the pedal down and it down shifted and accelerated so hard that when it upshifed, the serpentine belt through blue smoke out the back of the truck and the shock from the tranny was scary. Not reccomended to do that too often.
But overall, I have a very positive experience with the Superchips tuner. I sold mine last fall when gas prices were insane. Even now, super unleaded is 40-50 cents more per gallon that regular with the stations battling out for low gas prices. So I got rid of it. Plus in Massachusetts, we have OBD II testing at the yearly inspections. I would have to return the truck to stock every time. Got to be a PITA.
mine doesnt shift rediculously hard, i have the transmission set at just a little about stock and it does great. at WOT the belt does squeak a little when it shifts but i think its just because the motor changes revs so quick that the belt cant do the same. I actually bought a hypertech for my truck, i went to install it and it wouldnt work. apparently they dont offer one for my truck because its under california emissions, they cant program the truck and still make it pass emissions so they dont offer one. well thats how they explained it to me anyways...
