My TTA is having an issue at WOT. Bad miss @ 3400 RPM and about 17lbs of boost. Have replaced, plugs, wires, coil pack. Tried new cam sensor, map sensor, tps. Believe the problem is fuel related but not sure. If so I want to change the pump and install hot wire. Also have an 85 GN with a 87 donor car with ecm, harness, intake, exhaust, ac compressor, etc. to change it over. Have new turbo, ic, injectors, chip and usual upgrades. Would like to have an experienced tech do all the work.
