    415ci Stroker, difficulty starting after writing calibration

    I have an 03 Z06 with a 2 bar SD, 415 CI, 60lb inj and moderate non-lopey turbo cam. It starts just fine, idles and runs fine, however every time after I write a new calibration, it will start and die about 3 or 4 times before it will idle. This is a new engine and Im just now really getting a chance to tune it, so the ve table is not great by any means, but the LTFTs at idle are good. Im pretty sure it just needs something simple for afterstart enrichment or something but Im not sure. Any help or advice would be greatly appreciated.

    Thanks, appreciate it. I probably should have mentioned that the SD tune was working fine with the 5.7 that was in the car. The maf stuff is probably something that I missed when I converted it to SD a long time ago, but it would it would start after writing calibrations fine before and the only thing that I changed is the VE tables so far since putting in the 415ci engine.
