Well there you have it, those are the FACTS! lol. Go easy on the caps man. Both 2.5 engines i have run and idle exceptionally well. I'll admit the 2.5 is picky to tune. Once you get it, its gold. The 2.5R is alot nicer, and never gives me any problems. Just be patient tuning, and you'll get it. Sounds like big boy has 3 engines he doesnt know how to tune.

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
