Your using a vented blow off valve, that can cause stalling when coming down from high rpm, also you need to be flashed with a turbo tune if you only have a non turbo tune and you should install a knock sensor also if you want to keep your engine in one piece.

Hi, I have finally flashed the ecu, I used the original ecu of the spyder 98-99 4g64 and I had the problem of the fuel pump, I solved it by canceling the electronic regulator that is in the center console inside. Now I think I have to change the tps, I have read that I need the turbo version, so the next thing is the tps and calibrate injection map. Thanks for the help, if someone else can throw more information I appreciate it.
