I really would like to keep my JB+ right in between 1 and 2 o'clock but I can only get 91 octane around here. Are there any octane boosters that really work? I've had it at about 60% for about a week now (200-300 miles) and it is noticeably more awesome than the stock 50%. I was thinking of just ordering a case of Torco but if it doesn't really make difference I won't bother.

 

Idk if you have E85 in your area, I've been running a 30-35% E85 blend with the jb+ at 100%. I also have an intake, bigger fmic, 2.5" catless dp, and 3" catless exhaust system.

 

Don't be a sissy- crank it ALL THE WAY and if you detect a problem - back off'

I actually had similar questions? What is too much? What would I be looking for which would be worrisome?

 

Have you ever looked into the Manic tunes? Much safer than running the JB+, as the JB makes your motor run lean which can lead to issues.
I sold my JB+ which paid for a good bit of the tune.

Info can be found here if you are ever interested about the info on the Manic tune.

I use Klotz octane booster with the Manic tune. about $60 a gallon. Use 1 oz per gallon. Gets you about 10 tanks per gallon.

 

Has anyone used boosters before getting a tune/JB+?
