jb4 for 340 experiences needed
I'm considering getting the jb4 for my 340 but I have zero experience modding a car and I'm curious what kind of effects I can expect with this.
from what I understand, I get the power and torque addition without having to do any extra mods. I'm really not looking to go and do anything else to the car in regards to exhaust or intake. will that be ok for me to just plug and play and enjoy the added performance? should I be expecting any residual damage to the engine or other components due to driving the car with the jb4? any comments would be much appreciated. |

My opinion is that if you go the JB4 route it would be smart to wait and see what issues arise with the new B58 engine. Last thing you want is a dealer to screw you when something happens. That's just me though.
As for the mod, JB4 is about as simple as they come

Lots are running JB4 + Downpipes + intake + E85 making more power without any issues. With Jb4 only, you are very safe Lots of dealers on this forum including us offer 14 days money back guarantee on this product. Give it a try and let us know how it goes

If you do go for it, stick to the basic/recommended maps - you will DEFINITELY appreciate the bump in power. Just be aware that you may want to take it out every time you get the car serviced (personally, i would take it out). So that extra 15-30 minutes before and after a service can get old for some people. But once you have the procedure down its no big deal.

I ran into some firmware update problems but the support from the email was outstanding, found out it was the JB4 app on their end. Car pulls and I'm going to have to do some logs to see if I have any problems or not. To be honest, you'll take your time installing it at first, but now it legit takes me 5 minutes or less to install or remove the JB4. It's really that easy. Just make sure you have a T50 bit. |

Or even if it's not for service, say it's for an actual engine problem even though the problem has nothing to do with the jb4. If it is removed, would they still be able to detect it and blame it on that? |
