has anyone on here ran a 6lb pulley with a 4lb tune. i swaped out my 4 for a 6 today and am still running the tune for the 4lb. i talked to JL and he said it may be ok, just to listen for detonation.

I did it without an issue. My tune was actually so fat that it still was running rich with the 6lber.

What was your A/F and timing with the 4lb?

You should get a dynotune for that much boost. It may be ok while the weather is hot but as soon as it's cool one time-BOOM! Once you get your a/f and maf all tweaked you can swap pullies at will and it won't affect anything but the tires.
