Have you asked him why he recommends stock plugs?Usually I'd just listen to what my tuner says because they are the pros, but this confused me. I'm currently running a stage 1/2 tune (I guess)...mods are depo intercooler and aem dryflow filter. The tune I have gets up to 24psi. I'm currently running itv22 plugs and my tuner is saying switch to the stock ones. Won't I blow my motor?
