Two thing I'm try to smooth out before I install my 95 ZR1 trottle body and C8 intake. I don't want to compound probems before I make changes. This is my truck with TSP 218/226 and bolt on's.

1. I get alittle bucking when I'm at a light or parking lot and I let off the brake and just let it roll foward. It's worse on E85 than it is with straight 93. A couple weeks ago I tried lowering the VT tables on E85 only to what it was loging in torque. But all the did was close the trottle body blade and made it lunch really slow. I'm thinking its the driver demand tables????


2. When I'm in first gear and I let off the trottle to stop it revs the the engine. It does it worse when I have a load on it. Like when I'm pulling my 7,000 boat around slowly.
