By the way, Just in case you didn’t know, Mark Shead is the best there is for mapping so just follow what he says and save yourself a lot of hassle. (Not sure if he maps dta)

You also mention not wanting to spend much on a new ecu (which it sounds like you don’t need maybe) but running 400 bhp is rarely cheap in the long run as bits can break, intercoolers, exhaust, injectors etc...all begin to need upgrading.
