I have tried searching for similar setups but haven't found anything here. I am helping my friend change his head gasket on his '95 Cobra. He has a Procharger P1SC intercooled with the 14lb pulley. He also has bassani x-pipe, with a borla mufflers and 3 inch pipes, BBK headers (shorties), larger MAF meter(not sure what size), larger throttle body (not sure what size), 42llb injectors, larger fuel pump, Taylor wires, and a custom burned chip on the dyno. Now, he only got 350hp at the wheels. Shouldn't he be getting about 400WHP with the setup properly tuned. Is he missing something? What other mods would you suggest to bump it up to 400WHP? The motor is a brand new shortblock with forged internals and only 2000 miles on it. Thanks in advance for your help.
