if they send you one, your car will not start. you will have to perform a crank relearn
if you send them your pcm it will not be a problem
but i would recommend a proper dyno tune
Not always true. I've done many that did not set the 1336 code, so no relearn was required and the only way to gaurentee that it wouldn't need a relearn is to only reflash the calibration, if they did a complete write to the PCM, it had just as much of a chance of needing a relearn, as putting ib a differant PCM. I'd go to Frost, before going to Pcm4Less
PS Your vehicle will start even if a CASE is required, in fact it needs to run in order to do one
I sent mine into Frost after I got headers installed. I had a extra PCM that I sent into to tune and I didn't need to do the crank relearn when. It looks like you are just south of me, so if you need to borrow my extra PCM let me know.
