Did you check the timing?

 

[weeJohn]

Any other mods, FCD or ECU?

 

[Jambo2012]

Timing is fine it has manifold decat ,bov,hks actuator ,fmic but no fcd or anything

 

[weeJohn]

You sure its not hitting fuel cut and did you check the cam timing?

 

[Jambo2012]

Nope not hittin fuel cut mate n yes cams are fine

Have you done a diagnostics test yet for fault codes?

It sounds like limp mode and ecu has locked the timing at 10 deg.

Checked the diognostics mate and it's running lean Wat would cause this fuel filter ect...

I was referring to the test via the diagnostics port which is located in the engine bay.

Jst done it mate gave me the code which equals to 25 which is running lean how could I stop this?

Lambda sensor ok?

 

[weeJohn]

Usual suspects are O2 sensor if the ECU knows about it, (which it does) fuel pump, fuel filter and FPR.
