It's been said that running these coils with the larger gap will let you run more boost on pump gas, have you seen that at all shane? There's people tuning to ~28psi more and more, I'm curious to see if that's possible on a well setup car.

The startup, idle, and cruising gains make these worth it for me.

I don't know. Who runs pump gas in MN besides you, now that Kracka moved away?

I could possibly see some 28psi on the BP 93 pump gas that we have now. With the 91-92 swill that most of the gas stations around here sell, we usually had to pull so much ignition timing when we tried to run over 25psi that we didn't gain any power.

I could also see the the stronger ignition doing away with any light misfires under higher boost, the kind you really can't hear or feel that much but get picked up by the ECU as false knock or causes real knock(cars often detonate during misfires).

I do agree the startup , idle and cruising is better, but 40whp is crap unless there stock ignition is messed up. I would say 10 is more like it. Larger gap does mean better spark which means you will need more fuel to ignite.
