Capa Flash 2

[TY XR6T]

Hey guys. I own an 04 BA tubo manual ute. Have just brought a flash 2 from CAPA. Loaded on the generic tune of 8psi and took the car for a drive. It is missing under full boost at about 3000rpm and up. And has trouble even making it to 8psi boost. So I tuned the car back to stock and it is still doing it at 5psi. I have heard about trouble with the plugs?? Do they need to be re-gaped. And if so by how much? Now I know a custom tune is the best idea and will be looking at one soon. But I Am looking for a solution to fixing this problem first. any help would be appreciated. cheers

Could be ignition coils arcing out set of those on eBay for around 150, next is plugs you can buy them pre-gapped, theres a ton of info on this forum including the model numbers of what you want. Try and get rid of that generic sooner rather than later they're too much of a lucky dip.
