JB4 Tune Kit with 91-93 Octane

[sukhraj]

I was wondering how much WHP I can get with the JB4 tune if I’m only using 91 Octane or 93 Octane. I don’t have access to e85 up here in Canada so I have no other choice. With the JB4 kit and a intake i’m hoping to get at least 400WHP but is there any dyno charts with just 91 Oct or 93 Oct pushing that much WHP

Some guy told me he pushed 500WHP with a ECU tune using 91 Octane and a stock turbo, seems like bullshit to me especially if he isn’t using any E30 mix. He said it was WHP and not to the engine. It just seems super unreal and kind of bullshit

Yes, bullshit

What part of Canada are you getting 93 octane? And yes 93 octane and JB4 work very well together, depending on logs you could be good to map3 which will get you 400+, 91 octane different story, shouldn’t go above map1. Even our Chevron 94 is iffy on map2.

To make 500whp on 91 octane which can be done you need a ton of WMI and FBO. It's not going to be the safest setup for the engine either. But for those with crappy fuel WMI is the best option for making big power. The JB4 has solid WMI integration and safety making it easy to setup and run.

Toronto has it at a lot of places, shell, petro, etc

A all the Shell stations have the 93 out here now. It’s pricey but worth it.
