Alright guys, I've searched but didn't see a whole lot of comparisons or reasons one is better then the other. Using a MBC at the moment, but have been talking to my tuner about switching to GM3 ecu-boost. One reason mainly, is that I run E85 and it would be nice to have map switching fairly quickly without having to get out of the car and crank the MBC up or down like 20-30 clicks.

So GM3 guys, why do you like it? How has it worked out? Do you like it better then MBC or EBC? Has anyone switched back to the MBC/EBC after being displeased?

 

GM 3 port FTW

 

Ihad the same question because im getting my car tuned for e85 and 93 octane and i believe that it would get real annoying to keep adjusting the mbc.

But in the end it really matters how many times ur gonna switch.
If i stay with a mbc, im probably gonna make some lines on the mbc so i can see exactly where to turn it to.
