Hey everyone. I'm trying to decide what I want to do with my Supra next. I'd like to improve the performance/driving experience in general. Speed, sound, whatever. It's my daily driver. Here's the current mod list:

BoostLogic Catless Downpipe
xHP Transmission Tune
BMS jb4, using maps 3 and 4 as I switch between 93 and e30.
AmericanPanda front and rear badges
HKS drop-in filter (if this even counts as a mod)

Does it make sense to get the Fuel-It ethanol sensor, or to get a custom jb4 tune? Right now I'm doing math at the pump and am estimating the ethanol content in my fuel tank.

Or, do you think it makes sense to do something completely different? Let me know your thoughts.

You need to wait for the BM3 CustomROM feature to be released, or obtain a cloneable ECU - so that you can run ECUTek.

A true ecu tune is really where you want to be.

Also - you should be weary of modifying your daily driver. If something breaks, you are screwed and stranded.

I definitely will do something regarding a true ECU tune when I can, but was just looking for something in the meantime.

My wife and I also have a Subaru Outback that I could utilize if something breaks. I do appreciate you watching out for me, though!
