Well I took my brand new (less than 500 miles) GM Performance Crate Engine HT383 Vortec to the dealer Preston Hood Chevrolet to find out what was wrong and why the truck wouldn't stay running. I included a typed list of what was new: 383 stroker, fuel pump, fuel tank, distributor, coil, wires, every sensor on the motor etc. They said the new computer was bad, they said they would replace it with a new one. Well $687.00 later they told me my truck was ready and programmed for the old 1995 5.7 that I replaced. I told them it runs like crap. I am seeing black smoke from exhaust(unburned fuel), and slower than the old 5.7 with 250,000 miles on it. Their response was "It wasn't running when you brought it in but it is running now." Then it was that they would not program it for the new motor and if I put a chip in it my warranty on the now as they explain it remanufactured computer would be void. I will never go to a GM Dealer again, Total rip-off.

Live and learn. When I was in tech college in the early 90`s, the goal of each student was to work at a dealership. Anyways, we had this one student he was from Laos. He takes 2 years of college and graduated. We all knew he didn`t have a clue on what he was doing. So, our instructor recommended him to the local chevy dealer. So they hire him.
The first two cars he worked on, he screwed them up so bad both had to have new engines, needless to say they fired him on the spot.
The moral of it is, it`s hard to find a real mechanic anymore.

I would take it to an aftermarket garage that specializes in driveability.
Unless you have a scanner that displays data AND codes.
You will need to check for any codes that it may have but also verify the data on the data stream to make sure all the sensors are functioning and that the ecm is actually reading them.
Did you verify proper fuel pressure?
Too high pressure will make it run rich.
So will a fuel leak under the intake.

I am going to wait for the repaired chip from tbichips. Brian there seems to be really conscientious and knowledgeable. I just wish I had NEVER gone to the dealer. An independant garage could never have gotten away with what they did. Live and learn.

Gotcha, missed the new chip thing there in the earlier post. It would seem logical if you are sure of everything else in the fuel and electronic system is in order.

Most dealers and flat rate shops don't want to deal with hot rods, if they sell you the parts; it's in the hopes it works and they won't see you again. There's no surprise in their attitude, when these things have to be fixed it takes a lot of costly time that the customers don't want to pay for.

I realize that but nearly 700.00 to make a GM Crate engine run like a yugo is just a plain rip-off. I told them and provided them with a print out of what was in the truck. GM advertizes the motor as a drop in replacement for that "tired old 5.7". They should have said they did not want to make it run like it was supposed to, or been even more honest and said they did not know how to work on a performance motor. Everything except for the chip was GM. Now I know why only a few dealers are authorized to work on the Corvette ZR1. I believe DoubleVision had it correct in his response.
