Use a plugin ECU, I sell Wolf but Power FC are OK.
One of WAs toughest GTRs now has a Wolf Plugin because it has 100mm intakes
on the twin turbos and we didn't want to put air flow meters on them, the Wolf can use Map sensing well even with the 6 throttle bodys with their TPS to MAP change over, Even Autronic can't change from TPS load to MAP load only TPS v MAP.Every boost change has to have the ECU retuned But the Wolf can switch from TPS to Map sensing after a user defined change over point so you can tune it to high boost, you can then use a boost controler to raise or lower boost with out changing the tune.
