[QUOTE="KCTurbos, post: 1401932, member: 13852"] I was not exactly sure what you meant by this... but I can tell you that one of the BIGGEST complaints I have is guys trying to drive/tow like a stock truck with larger HP parts because they read on the internet that it tows just fine. People forget to metnion the "downsides" of some of these setups. THESE ARE REAL SCENARIOS WITH CUSTOMERS>>> I WILL GIVE AN EXAMPLE Customer: "Oh no, What should I do? I have 250/100s and your turbo. If I try to tow 12k up a 7% at 1800rpms in OD my egts climb up past 1200 degress so I have to let out of the throttle. I end up climbing the hills at like 30mph to keep my EGTs in check" Our Response: "Try downshifting and towing at 2200-2500rpms. Use the tow/haul button and try to keep your rpms up a little more. That will help the truck run cooler and cleaner" Customer: "but I want the best fuel mileage. I read on the internet that if I keep my rpms down then I will get better fuel mileage while towing. Also I can't tow at 2500rpms. That is almost redline. I don't want to hurt my motor" Our Response: These trucks tow much better at 2200-2500rpms. That rpm range will not hurt anything. Customer: "I tried what you said and it cooled right down but I am not happy, I think something is wrong with my setup. I read on the internet that guys tow just fine with this setup. Maybe I need to go with a bigger turbo or larger nozzles. I read on the internet that those guys have great luck towing with 250/200s and an s369 turbo. The larger nozzles make the truck run cooler and the s369 flows over 95 lbs/min. Do you think that will help? Our Response: :cursing::badidea::cursing: I think sometimes you guys don't realize what happens with all this info posted on the inernet... maybe this gives you a better idea. [/QUOTE]
