In addition to everything mentioned here, I would check the heat range of your plugs. Supercharging generally requires a heat range of 1-2* colder that stock (I run 2* colder). Having a heat range too hot, will definitely hinder the car's acceleration; will sound like the engine is cutting out and will be slow to increase rpms.
Ill be dropping it off to corvettes of dallas on saturday. Thanks for the help, I might tinker throughout the week on anything I can that might help but this guy said he knows those computers well so...
And as far as posting for the last year, its purely because my problems are intermittent and I have done things like opti etc so...
Thanks for your patience. I really am an infant. I hope to be the man at it one day but this car is almost paid off so once it is (couple months) im probably just going to go to town with it.
Problem is when you start adding mods like you have on there troubleshooting become a whole lot more of a problem. Tuning and after market splices and ignition add wild cards to it so that even the best have a hard time nailing it down sometimes.You will get it but if the guys who did the build can't starighten it out they should not be in the business.
And also my dealership said they can still get the ecm for $350?
I would be very leery of that. RedEasy knows what he is talking about when he said you can't get an ECM for these cars. Many people say they can but when they try to order they find out you can't. GM is on back order and Napa or Auto Zone or somebody shows some in stock or distribution center that they don't have.
