If you really want to keep your warranty and worry about NOTHING.. do nothing to the car. JB4 and flashing CAN void the warranty if caught. If you are hard pressed NOT to flash the ECU, then YES, JB4 is the ONLY way I would go. Proven product with active support from the company. John

Welcome !

We need these!

I keep mine plugged in all the time and don't have any problems

Hi, The car will automatically reduce power output when it gets hot. If you're tracking the car it doesn't take long for this to happen unless some things are tweaked in the tune. Of course without seeing a datalog I would only be guessing. If you can't datalog, the next thing I would try and...

Can you make a video?

I would reach out to Counterspace garage, they are in Cali and are actually in NorCal now working on customer cars. They've also have shown really nice power gains when using or Flex Fuel Kit on the Supra John
