Basically my engine was dyno'd at Harveys, I fitted the engine, installed Fuel system Hayward and Scott made the exhaust and everything else has been fitted.

Its 8inj on greens, GT30 on T6 ECU.

I can start the car if I hold the throttle down and have to hold the throttle at around 3 thousand revs to keep it alive, let off the throttle and its dies. If I rev up it hesitates and misses. If I hold it for long enough to warm up it settles down and will idle but is still hesitant and misses when I rev it again.

So far I have tried new plugs, the Pectel Monitor shows no errors and neither does descpro when I connect the laptop to the ECU. The fuel pressure in the rail is 53psi with the vac hose off and 43/44psi with it on. The throttle body position is 3 degrees.

The engine was fine on the dyno and was mapped and ready to go, the only things different will be my Exhaust, wiring loom, fuel system and intercooler setup. So either somethings a miss or I've disturbed something on the engine.

Any ideas for me to try before I trailor it up to Harvey?
