can you give us a little more to go off of? Is it holding boost? Boost coming late?

Do you get a lot of black soot out of your exhaust? Sometimes with the higher capacity pump you'll get too much fuel, which can cut down your power. It could also be timing. Getting a fuel controller and a timing light for a tuning session can solve a whole bunch of performance issues.

check the ignition timing.....follow the FSM and DONT use the loop in the back....put the inductive pickup around the primaries to coil 1 OR use a makeshift wire from the coil to the plug and use that...follow the fsm BS with the revving and unplugging the TPS reset it to 15BTDC and lemme know how that works out....most likely thats ur prob
