JB4 versus JB+

[Bug2th]

Also running JB+ On my 2021 locked ecu. Just FYI, I ran 12.2 @117 bone, bone stock. After JB+ install ran 12.00 @ 121. Same track conditions, with dial at stock position. I have it cranked now at 4.5 so waiting for car season to start.

It's worth it 100%. This season i'm adding a CAI and catted DP and then hodl until some sort of North American ecu unlocking option. If nothing by 1 or 2 years i'll grab a c6 z06

so I thought I read that a catted dp won’t do anything unless you had a tune - so with jb+ would there be potential for a lot more hp/tq or would other tuning be required that’s not possible with the jb+?

DP will add gains but to maximize the gain you would need a custom tune. JB+ will increase boost which means gains, but then again maximum gains are ALWAYS achieved through a custom tune.

In a nutshell, mods without a tune will add minimal gains but a custom tune will add maximum gains.

Can JB+ be ran safely on 91 Octane or were they set up for 94?

You got a 2020? If so, go with a custom tune with Ecutek. You won’t regret it!
