Improved towing
:argh:Any ideas on something to improve my shift points or power on my 97 6.5 half ton specifically on hills. manual waste gate, 3.5 inch straight, exhaust k&n intake, heath diesel lift pump, relocated pmd with heat sync, other than that stock as far as I know, fuel settings seem conservative based on the egt never went above 600 even in the hardest pull. Is it worth turning up the fuel? Or any other simpler tricks I may have missed? I pull my trailer thousands of miles at a time and speed drops like a rock as soon as it downshifts on a hill somewhat of an aggravation for me:argh:

ECM tune.
Heath,Kennedy or KOJO |
I'd go 4" diamond eye exhaust, it comes with a really nice DP, HX40 and a Heath towing tune to compliment it.
What kind of mileage is on it? Might be time for some stock injectors-NO marine or chinese crap, and 40hp injectors don't exist, marketing gimmick. What gearing do you have? |
4:10 gearing and I am looking at a heath diesel tune and Bosch injectors but until the price of oil goes back up I can't afford to do any more modification (my job security
Being directly linked to it), it' got 230k right now |
Wait I take that back the 4:10 is on the 99 I'm not sure on the 97 haven't had to tear it down yet
|
The sticker inside the glovebox says gt4 which should be 3:73 if the rear end hasn't been changed
|
I personally haven't been happy with my kojo tune, the torque converter kicks in at around 42mph... horrrible for pulling my skid loader, constantly pulling the shifter down to compensate. I told pat I hauled with it...

most reports are that KOJO is good to deal with about such matters. |
only 600* on the egts!? My 6.5 suburban will max out my egt gauge if i insist pulling my race car trailer. should be able to do 1000-1100 when you need it, if you are only down at 600* you either have a fuel supply problem or your stock tune is way more conservative than i thought they were. get a tune! you'll love it! :tu:

Fuel = power = heat |
How much boost are you making?
Sounds like you are getting an overboost and defuel. Try checking your codes. |
