Hi guys, I'm just trying to get a 6lt to run correctly in this roadster that a friend is building, (he has had to use an LS2 for Euro 4 compliance).

I have turned off some of the mil's that were flagging fault codes.

I've tried a number of different combinations in the Vat's but still have the same problem.

The engine starts and idles fine, as soon as the throttle is applied it will go to about 1800-2000rpm for a split second and then just sit at idle with no response from the pedal actuator.
Does anyone have any suggestions as to what I have over looked that would cause it to not go passed the idle position.

Cheers Scotty.
