Running an 05 RX1 with MPI supercharger at 7lbs boost.. At wide open throttle, I am only seeing about 10.8/1.. How many jet sizes do you think I can go down.. Sled has tremendous accelleration, but doesn't seem to have that top end charge I was expecting.. I'm thinking if I could get my A/F up to approx. 12-12.5, I would be making more hp, thus see some more top end.. I'm new to this boost thing, so any help would be appreciated.. thanks, Chad Ouverson

I agree with that post stay in the upper 11:1 range and don't make unreasonably long runs you should be fine. If you pay close attension your motor will even tell you when in danger. If you feel any motor start to loose power get out of the throttle immediately.

I would go down only one jet size at a time. I know that taking these carbs on and off are a real pain, but tearing the engine down is worse.
Everyone on this forum is running a little different jetting set up, even those guys that are running the same basic temps and elevation.
That seems to be the case for turbos anyway.
I know thats not the easy answer, but it probably the safest way to do it.
