It's essentially a piggyback tune with no warranty vs a flash tune with a warranty. So it comes down to flash vs piggyback.

Here is a thread with a decent (somewhat) explanation of the difference - https://f10.m5post.com/forums/showthread.php?t=1248685

If you are worried about a warranty get carbahn. If you want the best value for your money, get the Jb4.

Jb4 will make more power and more features

Carbahn is good if you want their warranty. Not sure if anyone had an issue ever though where they fixed it under their warranty.

The warranty thing is a marketing strategy. If tuned cars needed warranty work, all tuning companies would be bankrupt. Either from covering the repairs (Dinan, Carbahn) or defending against lawsuits (everyone else).

Do you wanna strap on some VR goggles and pound a fleshlight or would you have the actual girl?


Get a flash tune.
