i have a 100 shot in now, and as some have seen its running a little lean, but i want to try a 150 shot, im not an expert and i dont know if i would be able to run it once or twice and then go back to a lower shot, i will add some higher octane fuel in with the 93 if i have to, wont be able to get it tuned for a couple months so should i just wait, or what?

I'd wait for the tune, better to have to wait and make sure it's running right than go out and jack your motor up and cost yourself the price of a completely new setup.

 

Definately wait til you can tune for, especially if you think you're on the lean side w/ a 100 shot.

 

Personally i would wait to spray the 150 shot till you got it tunned if you are running a bit lean on the 100 shot. Even with Race gas there is still a chance you might hurt something even if it is only once or twice. I wouldn't recommend you spray a 150 shot till you get a chance to tune it.
