Cant seem to get a straight answer about which one is the go to.

JB4 vs dinan vs race chips

Goal is basically not nuke factory warranty for now.

I've had race chip and am running Carbhan.

Race Chip: Great performance #s from people who've posted. Why I got rid of mine? When in the most aggressive setting, shifts felt harsh. It's aggressive so I suppose I should expect nothing less..

Carbahn: Website #s are close (Race Chip slightly higher I think) but I found the Carbahn to be much smoother when in its aggressive setting. Been nearly 2 years running it.

Good luck!

I run racechip. 3.6 0-60, 11.8 quarter mile. I’ve heard people getting slightly better than that with racechip.

Was 3.9 to 60 and 12.4 quarter mile without the chip.

I remove before dealership visits.

I run JB4. I’m used to it and E30 is supported on map 2. I haven’t trapped it yet but these things wake up with just a piggy. You won’t wrong with any of them.
