Should I regap my plugs?
I have a sct 5* 91 octane performance tune installed and the plugs were gaped at .030 right before I installed it. Any reason to pull them and regap?
The truck seems to run fine and it gets decent mileage (could always be better). Only Issue I notice is a "miss" when its warming up at idle. But that seems to be fairly common.

It sure ain't normal - and I don't think dropping 0.002 is gonna make any difference. But - it IS cake to do, so won't hurt to try.
What's 5* recommend?
We talking fresh SP534's?

I thought it was normal. Read in a could other misc threads about guy experiencing the same thing. Goes away once the motor is warm.
I cant remember what 5* recommends. its .028 or .030. Ill have to look that up again.
Yes Brand new SP534s.

Put new plugs in sp-534's gapped at .030 and idle is much better!
5 star recommends the sp-534's gapped at .035 btw but I hear a lot of guys running tunes gap them to .028
