    sorry its mainly a stock 02 f body calibration with minor changes i copied from other swaps in the repositiory and ur previous suggestions and efi connections basic swap instructions
    its a stock bore lt1 with the lt4 hot cam, 1.6 rockers, ported heads ,lightweight valves, pacesetter longtubes, no cats, stock lt1 intake light gasket matching, stock injectors, pulleys, ported t body, built trans, trans go shift kit never had any problems with the stock lt1 tune except opti and prob lean
    since the swap i have hot start issues, rolling idle problems, hanging idle when hot on restart, nothing too crazy but as i said its just a whole different animal now the car used to drag gears depending on throttle pressure i could make it shift when i wanted ect i understand this is all fixable but i have no idea where to make changes
