I'm looking to upgrade my car from an LS1 based engine to an LS3 based one. This includes updating to a newer PCM. I'm starting to research what tuning options there are for the LS3 PCM's. I'm currently running the 1 bar custom OS on my gen 3 FBody PCM. Does anything like that exists for the LS3 based PCMs? If so, could someone point me in the right direction? If not, what is the process for tuning without a MAF in the LS3 based PCMs? I'd like to remain mafless.
Many thanks!
