cam timing out somewhere. either cambelt position out or the cams out of line? sounds like the most likely problem

Tps problem cross the 2 low pins of the tps out put it in dag mode and set the base timing to 10"btdc , if that dose not help check ur tps wiring to the ecu , if it helps reset ur tps and make sure it's working ok

On the TPS itself, where it plugs in there are pins, the bottom 2 is the ones you look for.

thats what the dyno man thought but its all spot on

 

[Joelean]

whats the mileage/health of the engine? compression etc? what are the intake temps?

 

[beany1588]

800 miles full rebuild all spot on

the guy who rebuilt the engine said that he took of the solinoed for the hi low turbo boost on the dash wouuld that cause a problem with the blitz turbo booster and or cause a fault with the ecu.
thanks

Whats the Blitz turbo booster, a boost controller? If you are getting 1 bar then it would be ok and should not affect the engine controls.

 

[beany1588]

sorry its a boost controler

What topmount is it dude?

If you and the tuner are sure the timing is set correct, it's worth having a look at your knock sensor and it's wiring.
