[Blk340i]

I bought my 50i about two months ago and it is decently quick from the factory but I felt it just needed a little more. I went with the JB4 to start and I just couldn't feel much difference and the logging wasn't working properly so I decided to explore a flash tune option. After a few weeks of research, I ended up working with Lalit from DME tuning and purchasing there flash tune. Although it is significantly more $, it is worth every penny. It should have come from the factory like this but I understand why. The tune made a night and day difference and I am very happy I went this route. Lalit is top notch and has been great throughout the process. Being that I'm local he came to my house on a Saturday with his business partner Mo to install the flash. They were in and out in about an hour and now this Grocery hauler pulls extremely hard.

They make a g series JB4 but I just couldn't get it to work properly and with the logging etc and I didn't feel much of a difference. With the flash it is night and day.

Stage 2 - burger tuning has since reconciled the issue with the JB4 so I have that installed also and using it mostly for the gauges.

Hey, thanks for your post.
By chance, would you be interested in selling your JB4 for the 50i?
As great as DME sounds, it's out of my price range at the moment (have so many mods on the list already lol)
