I will apologize in advance, I know this question has probably been answered many times but I have been searching for over a week and think I know the correct combination that would work for me. Thank you for any advice and sorry for asking this question. I have a 2000 F-350 srw ZF6 Valair single clutch, it has 200,000 miles on it and removed the ebv pedestal and installed a GTP38r turbo and regulated fuel return, big air filter and 4" straight exhaust and replaced the 285/75R16 with 305/70R17 wheels. My family and I recently took a trip to Colorado with a 12 foot flat bed and a Polaris Ranger. (Light load for a one ton) and would have to back out of the throttle while pulling a hill because egt would get to 1200*. It is currently tuned with a superchips tuner. I want to ditch the superchips and install a TS chip and single shot injectors. Stock AC's, 175's, 160/30, 175/30? But cannot decide which ones. It is not a race truck just a daily driver that frequently pulls a gooseneck stock trailer or a full size pick up/tractor on deck over flatbed. What injector is going to work best for low end torque and EGT control. Thank you for your input.

 

What setting did you have the superchip on?? If anything above "tow" your EGTs will spike big time. With my Superchip in "Performance" setting I can get EGTs to hit 1400 by the time I'm to 70 mph with just the pickup. In "Tow Performance" I've had to let off with just the pickup in the hills before even.

Did you downshift to get more air flow through it to cool it down at all?

TS won't be any better for EGT spikes either, I've had Superchip and TS. The TS is better than the Superchip but not by all that much. In fact my TS chip is currently in the mail on the way back from getting reburned with better tunes from Tony Wildman.
