Ok so here is my problem, my car was missing when i was turing on boost and running 0.8bar (started to happen about 1-2mins after running the car hard with boost on) with the ebc and running stock boost the car would not misses, i would run it hard all the way to redling and it wont have a problem;
So this weekend i change my plugs as i am running in a drift event this week and i need to be able to run boost.
Now i put normal Copper plugs, and gap them to 0.6; Taking it for a test run the car started to misses in every gear above 4000rpm on stock boost, with 0.8bar the car misses as soon as it hit 0.8bar on the boost gauge.
So i took them out and regap them too 0.8 and it has the same problem as above,
Now i check my old plugs they were gap at around 0.5.
I am majorly confused because before i change the plugs it would only miss under the condtion of 0.8bar of boost now it happens under stock boost.
What else could the problem be and how can i check if it is that, i will be taking the car to the mech 2morrow but i wanna get an idea before then
Thanks Michael
