DON'T WASTE YOUR TIME !!!!!!
TRX 2.5 IS A VERY FAST ENGINE BUT IT WILL NOT HOLD IDLE EVEN AFTER THE RUN IN .
I OWN A T-MAXX AND I'VE CHANGED 3 ENGINES ALL OF THEM HAVE THE SAME PROBLEM.
FORGET IT !!!!
DO NOT WASTE YOUR TIME TUNING .
SWITCH TO A SIRIO 18 OR PICCO 21 MEDIUM BLOCK. OR IF YOU CAN PAY MORE SWITCH TO A XTM CONV. WITH 24.7.
SORRY TO UPSET YOU BUT THIS IS THE FACT
