boost issue still ongoing
does anyone know if a faulty knock sensor could somehow retard ignition? Also does anyone have any good spec's on gapping plugs...

have you checked the ECU for errors?
you'll have to tell us more detail what is actually wrong with your FD. by the sounds of it you engine splutters when it hits boost. this can happen if the MAP sensor is disconnected

My boost is like 12-11-14, the spike is ok because i know i can fix that by porting the wastegate. But when the car boosts it does not accelerate, the boost slams up to 12 lbs, but the car just does not move. My mods are as listed: new Pineapple Stage 3 motor with all new and cryo-treated components, oil mods and loop line, only about 1800 miles on motor. Brand new 99 efini turbo's, fluidyne rad, cosmo fuel pump, new oil injectors and injection lines, M2 ecu, M2 downpipe, greddy catback, magnecore 10mm wires, and new plugs, greddy blowoff valve, K&N filters, turbo timer, c's short shifter, RPS street clutch, ACT 9.5 lb. flywheel, my fuel injectors have also been flowed and matched by Marren Fuel injection at time of rebuild. I basically went all out and did all of this during the time of rebuild, but I had the ecu and 99 turbos on the car for around 125 miles before the motor blew, but the ecu wasnt enough fuel and thats why I upgraded the pump and injectors. Everything ran fine before disassembly, and with all the upgrades should be a really strong and reliable car, but i cant sort out my boost issue. I know its ignition, but i cant seem to find the source. I have done plugs, coils, wires, starter, igniter, crank sensors, etc... I need help!!!!

Did you upgrade the injectors or just have the stock ones cleaned and flow balanced?
