How many head gaskets were blown to over boosting? You can over boost with or without a tuner. I did running stock. I think a boost gauge is a must on all 6.0L before 2005. I believe you can overboost more easily with a tuner... but that is up to the driver. Stuck turbo vains will cause overboosting which I believe is caused by the EGR system. This too will blow the head gaskets... with or without a tuner. I won't use a tuner because I can't afford one and I don't trust my foot! I think everyone of these trucks needs aftermarket gauges to monitor the engine and transmission. This will help prevent blown head gaskets with or without a tuner. Just my opinion.
WOW! I have never seen this much whining about a poll? Hey if your HG's haven't popped yet, good for you! Just trying to get some info on what type of setups have more HG issues, simple as that..... I expect more people have not had HG issues. But with the few who have it would be nice to know if they were modified.
Mine have crapped out and there is still a problem with the poll despite the fact that this poll would apply to the fact that I had head issues. I can not definatively say(and probably more then likely no one else that has already voted that running a tuner caused there head issues) that the tuner that I ran is what caused the problem or that it was that way from stock or that I caused warpage with the heads while I was driving the truck before I put the tuner on. There isn't an option that expresses that on this poll either. I know it's a no win situation, but unfortunately it is what it is.
It will be good to know stats. Some folks get pretty sensitive about this issue though. I bloew the gaskets on my 03' and did ARP bolts before it was the "kewl thing to do" and I did bolts on my 06' before I put a tuner on because we all know that is one of Navistars weaknesses.
