Ok so I have a base tune loaded in my EMS and it idles great but then when I try to rev the motor up it just sputters. I have my spark plugs in that I just bought they are NGK BKRE8EIX I'm hoping I didnt foul them tell me what you think.
My question is if this looks ok should I get some cheaper plugs to drive on until I get tuned like a bkr7E since those are $2 each and these are $10?
