Did you check the plug gaps before fitting? Incorrect gaps canrun fine on normal driving but will fail under load.

@T-dogChecked timing yestarday and that's spot on, @gorganl2000 Plugged in the carmanscan diagnostics yesterday also and it said the map sensor was reading 8psi constant even withought it running so not sure if that's right, @gibby1980 running dastek 

 

Try changing that map sensor and do a diagnostics test again. See if it's the same. Does the software for the dastek show the same 8psi? I would see that in tunerstudio for the Megasquirt. Confirm if the dastek is tuned for the higher rpms/boost?

Ok I shall do that whenever I can get my hands on one, How would I test that? It was running fine untill I was going up the dual and suddenly lost power and then started spluttering when in boost
