The IS series cummins will NEVER be as good as it predecessor....the N14! I currently run an N14 Celect Plus 525 and I LOVE it! Ain't another tandem truck around here that can run with that KW
I got one of those too. A 98 Kenworth T600 with a 70 something inch sleeper and an N-14 with 80,*** on a pitsburg power overhaul, 526 dino'd with a 13spd to put it to the ground.
the ISX is in my 2007 INTL 9900 daycab michigan special.
