Is this good information or bad?
We've got a reasonably new (12 months) diesel repair and performance shop in town, so I stopped by today and visited with the Owner. He seems like a very knowledgeable guy, but he did say somethings that concern me.
He asked me what I was running on my truck (Spartan, DPF Delete, EGR Delete with Elbow and GREEN filter). When asked what tune I run as a Daily Driver, his comment was that running a 250HP tune all the time wears out the inside portion of the head gasket (next to the cylinder bore) and is one of the leading causes of head gasket failure on the 6.4. I explained that I run the 250 mainly for the fuel economy and rarely ever "Get On It". He said that it didn't matter and that since I've been tuned with the 250 for 47,000 miles that my head gaskets are a ticking time bomb.
He went on to ask if I towed and what tune that I used. I told him that I also run the 250 and have my gauges set to warn me in case anything gets out of whack. It has been my experience that the difference in boost pressure and exhaust gas temperature between the 210 Tow Tune and the 250 Early Lock tune is negligible. Once again, he stated that I was really hurting my engine. He also said that when towing an EGT of 900 degrees for a prolonged time or an EGT of 1,200 degrees for 60 seconds or more can cause catastrophic results.
Does this guy know what he it talking about or is he full of hot air?
