Message: [QUOTE="Wrecker, post: 1519091, member: 12157"] Here's the background of the situation to where I'm at now. 17 F350 DRW on 37/22's Ez Lynk, Tyrant CAC sotf tunes, No Limit intake, 5" exhaust, and egr block plates at 3500mi About a month ago, hooked up to my toyhauler for the first time with this truck, 43' Voltage 17klbs, to head from Grand Junction CO to Moab. Sotf set to 1, truck felt like it should have more power, egt's seem to run hotter than I remember with my 14 truck. About an hour into the drive I hear a massive hissing noise from under the hood that’s getting louder and coast to a rest stop. Get out and the secondary cooling system is blowing all the coolant out of the overflow tube. Figured the hissing noise was just the sound of the coolant spraying out. Fill the secondary tank back up, appeared to only dump what was in the tank, maybe ½ gal. Attempt to pull back on freeway and massive hissing is still there, plus no power. Pull off and look around and find there’s a 1” hole melted in the back passenger side of the plastic intake manifold. Pull the cac cold pipe and the cac temp sensor is melted also. Dur to the SOTF tunes, this sensor isn’t hooked up which is why I never saw anything or got a CEL. Have everything towed home. Get No limit full egr dlt, ccv dlt, Midwest piping kit, and No Limit intercooler ordered up and installed on truck. Get the truck all put back together put about 1k mi on it working and head from Grand Junction CO to St. George UT to pick up my new boat, all seems to be running good on SOTF 5 setting. Go to leave St. George and get about 1.5hrs out of town towing the boat up a hill with the cruise set at 80 and the hot side intercooler boot explodes, doesn’t blow off the clamp actually blows apart in the middle. Also, the powder coat on the hot side turbo pipe is starting to discolor right out of the turbo. Gorilla tape the boot back together, hook the boat up to my dads truck and limp it in to next town, find a boot that kinda fits and baby the truck 5hrs home not towing anything. Get new HPS metal ring reinforced hotside boot ordered up and decide to load up a straight non-sotf tow tune so I can plug my cac temp sensor back in and see why the temps are so hot. Drive the truck and see right off the bat from sitting cold overnight my CAC temps are running 40deg over my IAT cruising at 80mph unloaded, roll into wot and climbs to 100+ deg over IAT (to about 200deg) within about 5-10sec. Getting a P026a code within 2-3 min of driving the truck also, “charge air cooler efficiency below threshold”. Clear the code, comes back right away every time I drive the truck. Load the non-sotf Extreme tune and get the same temp differential and code. My boost psi reading also jumps up and down about 4-7psi rapidly around whatever the actual boost psi is, still seeing peaks up to 37psi though. Replace CAC temp sensor, MAP sensor, EBP sensor and try again, same results on everything. Both coolant tanks haven’t budged under the max line this entire time either and it’s been about 2000mi of driving now dealing with all this crap. Have several buddies with 17’s and just dlt tunes and their IAT/CAC temps stay with about 4 deg of each other while cruising and 15 deg at wot and their boost isn’t bouncing rapidly. Monitor turbo vein position on ez lynk and they are ranging 0-100% just like they should, exhaust brake is working, and you can hear them change at idle due to the rumble tune when it briefly hisses every so often. WTF is wrong with this truck that even after replacing everything but the turbo the temps are so high??? Bad turbo?? [/QUOTE]
