Did one recently with high comp and 438s, although strangled by the overly silenced exhaust it pulled very hard indeed.
I don't see how you could see an aftermarket ECU as a downside in any way, the stock ECU is so inflexible it's very fruatrating to try to work with. Even a map that's had a lot of time and attention spent on it is never any more than best guess, to do more than that isn't possible. Pete should already be running on super, that's what it's mapped for and I told him to use.
438s will work perfectly with ITBs
In any case, that's not the route I would plan, but that's between me and Pete to discuss![]()
Hi Dan I'll drop you a mail re this, still got you other mail, I'll reply to that and see what I can sort out.
