turbo 1.9 problems HELP
I have a 1.9 motor and i put a turbo on it. the motor has diamond pistons and crowder rod its all build to hold over 20 lb of boost it has a MSD boxs, crank trigger, innercooler and a FAST computer. the motors has been tuned on a dyno and has been running great until now
the problem
when reving up the motor when it hits 5000 RPMS it drops the RPMS back down to about 3000 even when floored.. I replaced the crank trigger sencer and the TPS what esle could it be ?? compression test is good and water test is good

You might have insufficient fuel delivery, which could be due to a partially clogged fuel filter or failing pump. Try installing a fuel pressure gauge.
You could do a quick test by simply holding a dial type tire pressure gauge on the fuel rail Schraeder valve and have someone rev the engine to recreate the problem.
I had this problem last year in my normally aspirated Escort. I'd rev it up to only 3000 and it would die as if the ignition key were turned off. If I held the gas pedal down, the engine would slow down to 2000 rpm or so and then catch again.
