How-to after major engine upgrade?

[Garry]

OK, I expect to get back from vacation to my freshly upgraded Firehawk ...:fluffy: It had been stock, apart from running on COS#5 with SD ... see below for list of upgrades ...

Anyway, what's the best way to get started with re-tuning the PCM? I've checked the available tunes, but none seems to be anywhere close to my setup, apart from the fact that those are mostly standard PCM OS, not COS5 ...

Start with the AutoVE, but in your case I'd use a 7-10% across the board rather than 15%. Once your air mass model is complete, you can go after the MAF and spark

OK, will take it slow, go 10 to start with in lower RPM ranges first and see how the car reacts. Hope it's finished anyway, should now tomorrow morning ...
