ECU tune for gs400? Anything other than Jet???
 

I am looking into getting my ECU tuned/flashed. All i can find is that you can send your ecu to Jet and they will flash it/program it for you. Ive been searching for a while for something for my 1999 gs400.

All I can find that says its made for our cars is Jet, and those fake ebay/Made in china and we all know those do not work. Is there anything OBD2 plug and play that works. I have an intake and full exhaust system now.

I have heard people hooking up a Apexi SAFC or a NEO. How hard is that to install and what else do you need to do to " tune" it. Are there any dangers with this? # Gains?

What would be the most economical/safest method to pursue, leaving it the way it is can be an option too.

Anything????????

This is a 430 but good read

Thanks for that 21. I read most if those treads, wanted to see if anything recently has been introduced.

Seems like the only decent option is a safc
