tuning

[Frankenstein dsm]

ok have 91 fwd dsm mild built head .20 over bottom end chipped ecu with afc2. Chip made for 660 inj and evo maft. To started up ran 3 5 min then outta know where just shut off wouldn't start back up disconnected all plugs let it sit then plugged everything back in started right up then of again. Just wondering if safc is messing with the chip or did it need a tune

Your description isn't very specific. Does it sputter and die? Is it starving or fuel or choking on it? How confident are you in your chip?

Even with a chip you should get it tuned to make sure your not starving the engine of fuel. Running lean is the last thing you want to do. Unless you want to spend some money on a new engine.
