A few weeks ago I wrote asking why my turbocharged 289 had such a problem pulling 12,000 lbs. Over a month ago we changed the plugs and a few other things. One plug was dropped but we didn't notice that it closed the gap completely. It was about midnight when we did this and we were under the gun. We drove our truck and trailer pulling at least 10-12,000 lbs all the way up to donner summit and back down. We had trouble with it missing and detonating. I have made a few other heavy hauls with the truck since then and just last night checked the plugs and one wasn't firing at all. I went all the way up there on SEVEN cylinders. I still have trouble with getting more than 3 lbs of boost. If anyone has advice I'd appreciate it. I was also wondering what I could do to improve the octane in the fuel? Thanks.
