I have been on the dyno with the 50shot and tuned and the injector duty cycle was only 72% and afr was under 11.5. I also have 100%methanol shooting under boost. I recently jet'd up to a 75shot at the track (no dyno check) and ran fine.

My question is can I safely go to 100 shot for a pass or two or do you think I should have my tuner check it out on the dyno first?

I would run straight 100-103 octane as an added safety for the 100shot.

I dont want to have a problem but at the same time I kind of don't want to wait to see the tuner cause he is travelling alot lately.

Do you have any way of monitoring your A/F? Like a wideband? Or are you running around kind of blind? I'd say if you can monitor and log your A/F, see how good/bad the 75 shot is. If good, then step it up and see if that's good too. The only problem I see is that since you're blown, nitrous, especially a dry shot, may max out your injectors quicker than expected. I'm sure there's some mathematical way of figuring it out, but it's not a risk I'd take.
