It will work on 91 and better fuel

Meant to work on stock cars, if you are adding mods you probably are better off going with a JB4 instead

I don't believe there's any room left to make more power on 91. Terry's stock 91 dyno and temp show it's maxed out.

Agreed, but OP is in NJ so 93 is going to be used

I was wondering the same thing. I use 93 so it may show some good gains. For now I am not planning any power mods and for $200....my question is, is it worth it?

Thanks for the reply guys. I already bought the JB+ but I don't have the M2 yet. I will run 93 for sure. I plan on upgrading everything in the future though. I'm hoping for JB, enzo, pure stage 2 turbo, sport cat / downpipe, new charge pipes. I also already bought H&R springs, still need to figure out spacers.

The thing is, I'm blowing my load, wallet-wise to pay for the M2. So I figured the JB+ would be good for a few ponies (and cheap HP), but I haven't read much ///M2 specific data, which is why I started this thread. I also bought a K&N air filter, which everyone knows is good for at least 100whp, LOL!

I recommend JB4 with Enzo tune since you will be needing the Jb4 datalogging capabilities

Thank you, I'll certainly keep that in mind. I also might have another tuner to use instead...

We shall see. I'm thinking at least a year before I can even start with the turbo/tuning upgrades. I'll bet some kind of kit will be out by then.

You are welcome, i meant to say when you do a flash, get the Jb4 for boost and datalogging

We/I need to hear from someone who has actually used the JB+ before I buy it.

I've posted a number of times on the great value of the JB+. I use 93 and it's a great improvement for the money, especially low end grunt. Can't go wrong with the price. I've done a number of mods, so I've maxed out its effectiveness. Still deciding on which system to move up to, JB4, Dinan, ECU flashes, etc.

Looks like there will be at least 3 ecu flash options soon. I am hoping/praying for a back end flash that works well with a traditional jb4

Thanks for the response. I will most likely pick one up. Do you know if any codes will be stored in the OEM computer with the JB+? As far as any warranty issues coming up when it gets taken to the dealer.

Shouldn't be any. Just disconnect when delivering for service.

Def don't want "low end grunt". My guess is dyno was unimpressive and they decided not to publish.

Not sure what you are expecting for $199.

Why would you NOT want low end grunt?

Because the low RPM boost is adequate.
