I have a 91 z28 running 730 ecm with the 8D bins right now im using the stock bin with only slight changes made like egr, a.i.r. , vats , idle , and fuel injector size. But the motor i built needs a modified bin i know the spark tables and ve tables need to be adjusted quite a bit but dont really know which way to take them. i do have a chip burner and laptop with a link to the car . Currently im using Tunerpro Rt and ecm852 as far as software goes. Really i just need someone to point me in the right direction on how to go about adjusting the tables and how to know how to adust them for what the engine really wants. Or if anyone has a ve table or any other table that has been adjusted that might help me get to where i need to be would be great.

My engine is a 355 forged internals 4bolt block, dart pro 200cc ported heads, supperram intake , 58mm TB, 25lb injectors, headers, nos, stall , msd, comp cam Lift In .576 Ex .571 duration In 280 Ex 288 lobe sep 113.
