Hello Jb4 Or No?

Hey so I'm new to this all and I have a BMW 335xi stock. I've done all tune ups at BMW and had it fully serviced already! I wanna know if I should get JB4 or not? They are like 500 bucks plus who actually tunes it for you because I sure don't know how to? How much am I looking at in coat to install it? Any help or tips would be appreciated

I suggest you read A LOT more before doing any sort of modification.

This cars need more power. The JB4 helps a lot with that. Install, leave on Map 5, done. Then do research to go further (Backend via BB/MHD and supporting mods).

Yes, but only if you can install yourself. If you can't follow the (really really easy) instructions included and posted on their website, you shouldn't really be modifying your car.

Well you can do a stage 0 then stage 1 mod to it.
Stage 0:
*Walnut Blast, Plugs, Coils, Injectors & Non Run-Flat Tires.

After that your car should feel much better, then if you want more you can go to
Stage 1:
* JB4 & Charge Pipe

Both aren't to hard to install. It'll be much faster, but won't completely scare you.

JB4 is a great tune and its all pre-set ready to go out of the box. Its a 30-45min install and can be done yourself or any shop should be able to do it.

Will come defaulted to map1, which is perfect for your stock car. Consider getting a DCI with it as well.

Shoot me a PM if you have any more questions.

Mike

a tune is one of the most popular first mods.

JB4 wont require any extra tuning. The tunes are already preset for basic modifications.

So it's plug and play.

Jb4 is the most popular tune . No extra mods needed, it will give you instant power, lots of features and its proven to be safe.

It will make your car a lot more fun to drive. I strongly recommend you give it a try.

Check out the vendor section for deals on the JB4
