S4 rx7 improper pfc install
Just wondering if anybody knows the repercussions of improper install of the pfc with the banzai adapter harness? so the car was running and driving got maybe an hour run time on it and it messed off on me. Basically it's flooding itself bad like kicking fuel up into my intake runners then leaking though my lim gasket. Racked my brain over this. Just so happened to be hanging out with a friend and he had the pfc install directions and I got to reading and realized that the cor wire the ks wire were not hooked up and the tps wires were not spliced together. Now I guess for my set up in case it could be something else . 88 10th ae rebuild 2500km on it large Pinapple racing street port. Stock 550cc high impedance primary injectors. Id2000cc high impedance secondarys. Borg warner s366 Turblown manifold 2 40mm turbosmart comp wastegates. Modded fc trailing coil 340lph fuel pump. The car still runs just floods itself really bad then blows out that gasket and creates a huge vaccum leak can't rev past 2500-3000 rpm but can let car warm up shut it off turn it back on and for about 10 seconds can rev it all the way through the rpms then back to 2500-3000. I have the fuel tester jumped on the engine harness that's how it is running as well obv cause the cor was not hooked up.the power fc is loaded with a 1680cc fd tune on it for a base tune just to get it on the dyno. Any help would be great about those wires not being hooked up or any other info thanks.

Hook up the wires. You know it is installed wrong.
If you have someone else's FD tune on your FC with the wrong injectors sizes being used and incorrect slopes the car is not going to run properly. Chances are you have the wrong map sensor selected also.
