I have a Blitz Access Ecu for sale atm. Only because I am upgrading to a stand alone ecu to run launch control, shift cut etc when flat shifting and all those nifty little features. I was running 18-19 psi on Blitz K1-200V with the Blitz Access ECU with out any dramas at all. I was just running a Supra Fuel pump, FMIC, mani, dump and exhaust.
