That last time I had the car on the dyno with the 125 wet shot my AFR was 11.2, I was wondering if I step the nitrous jet size up one to the 150 hit would that bring my AFR closer to 11.7 or so. I've been wanting to put the 150 jet in anyways but I just want to make sure I wont be running lean.

I'd run it at the track and see what it nets you. If the mph gain looks good, leave it. My stuff ran ok at 11.5:1. Sounded good, looked clean, plugs looked happy..No need to go pushing it to say your A/F is .5 higher... I don't think anyone would say chasing an A/F number is smart.

Small steps with whatever you do!
