'94 Z28 track car
I I've got a 94 Z28 that's track prepped. It's got a 383 stroker motor with 12.2:1 compression. It seems to have an ignition problem under acceleration. It will hesitate, sputter and sometimes cut out completely for a second. It's got the factory ECU but has been converted to MSD ignition. Don't know the tune it has but not tuned correctly. Any ideas on what the issue or issues could be?
Thanks,
Tom

What MSD components - Opti?, coil?, wires?
What spark plugs, and what gap? What size injectors? What cam specs?
What is the history on the unsatisfactory tune?
Have you checked the fuel pressure? Have you scanned it for codes?
