In my opinion, you will still need a piggy back on the ECU as the Mines is just a slightly altered map from standard, not enough to risk running it on a built engine in my opinion.

 

In regard to the injectors, you should be fine at 1.2 bar on 440cc's as this is what all the j-spec BPU's run, however, with hybrids, you can go past 1.2 and to really see the benefit of the hybrid turbos, I would be looking at using 550cc UK spec injectors.

 

ETA: There is no point putting the piggyback on the mines ECU, you would be best selling the mines to recuperate some monies and sticking a piggyback on a stock ECU.

Whats tho going rate for a pre faclift, manual tt, J-spec mines ecu these days around £400 or something?

 

Also with the turbos being hybrid and being able to withstand running higher boost levels, would it be benefitial to remove the 1.2 bar restrictor ring from the de cat pipes? Or would i still get to much of a boost spike for them to handle.
