JUBU and other topics, a combo thread

[TFS]

I did not have a good experience with JUBU - I was involved in the first group buy for the JUBU ECU.

Me neither! But I cant say much as they know how to shut your mouth

~3psi more boost at 2.8"

Personally I'd get the 10 bolt version that requires a hub as well as you're significantly increasing the spin rate. Lower size than 2.8" requires going through Jokerz (they have a deal with ZPE). This is useful at higher altitudes or if you want to do a bigger build.

Here's my 2.8 and 2.7 currently disassembled.

Thank you again.

Would this require any ecu tuning to make work?

Would we expect JB4 to work with smaller pulley?

I notice you’ve mentioned Jokerz a few times, which hasn’t been very broadly discussed on these forums. What’s your opinion of their work?

Your posts are among the very most informative on this forum. Much appreciated
