Wondering if someone can help with a problem I'm having with the car.

Basically the car was mapped and dyno'd at 260whp, it sat for a couple months and went back to the same dyno for a rolling road day and only made 230whp.

Any idea what could cause a power loss like this, I've checked everything i can think of, even replaced turbo as it was starting to go, but its made no difference.

Hey guys thanks for all the replies.

We are sure it must be a problem with the car, as the same mods on other cars make far more power.

Car has:
OMEX 600 ECU
John FRS Turbo
Airtek Intercooler kit
Full turboback 3" Exhaust
Fuel Pump

The weirdest part is that it seemed to be hitting a wall at 230whp, with boost at 1.2bar and 1.5 bar there was no increase in power.
