True, I have a superchip in my 1994 SLE and I LOST power. I put my stock chip back in and instantly gained back power. I almost think it'* better than before. I don't know if it'* due to it relearning the system with all the mods whereas before I never reset the battery when I did the mods. Mostly a seat ofthe pants feel, but I could swear it'* faster than before I had the chip and definitely faster than the F'n superchip.
I called superchip and asked them why my power and fuel economy were down, as well as my shift points and the rev limiter still being the same, and they said "Oh, really, that'* wierd. You should drive it 100-200 miles and then call us back and let us know how it'* doing then." I then told them that I had driven 750 miles and things only got worse, and that was not happy with their product. Then they told me to send them $125 and the chip and they'd fix it. Oh yeah, I really want to give you another $125 to do what was already supposed to have been done.
