Ok...Basics:
2001 2500 Auto. with approx. 312000 on the odo. 2wd.
Purchased the truck in Nov. of 07 with 253035 on the odo.
When we first bought the truck it was clear "something" had been done. It was throwing out some pretty serious smoke and was decently fast. About a month if that later, my lift pump and fuel pump died and we had a new pump and lift pump installed. Truck still blew a good amount of black smoke. Before install the computer was checked for DTC's and wire tap.
About 6 months ago from today we tried using a max micro tuner from superchips on my truck, superchip accepted my vin. but it was obvious that no performance was added, (superchip stated it was a successful upload). When attempting to pull the chip off, the programmer stated failure and my computer started throwing DTC's. So for a failsafe we took the truck to the dealership and had my computer flashed (very important). After having the computer flashed I still had the same smoke content and horsepower. [Note that the entire time I have had this truck I was under a huge impression the original owner just installed larger injectors].
So...this past weekend we borrowed a friend's smarty, he pulled it off his truck and we tried it on mine...smarty read a successful upload, and I could tell a slight difference (little more smoke and acceleration from about 1000 to 2000 r.p.m.). We went to pull the tune off my truck and OH MY GOSH at the horsepower LOSS!!!! I barely put out any smoke now and I pulled a trailer to the strip (could hop right up to 75) but on the way back it struggled obtaining the speed limit (24 ft. gooseneck trailer).
What has happened, better question, what was originally on my truck?
Please help.
Thank you.
