I agree with PSJ you are runnig it to rich and fouling the plugs witch will act just like you are talking about and TR6's foul very very easy for some reason. You say at part throttle it is 10.8 that is just way to rich I would at least move it to an 11.2-3 to 11.5. especially at part throttle it should be a lot leaner than that 12-13's when you are under part throttle. I just think you are fouling the plugs and you might try a TR55 since you are running such low boost. They won't foul as easy, but you are going to have to watch the KR and check them to see how they look after a few miles etc...

WHAT? no its never had any issues like that...

the blazers just been sittin up till now ive been to busy to mess with it.

hope to tear into it in the next week or so.

Im thinkin since it has stock valve springs and i am spinning it higher than stock RPMs for a 6.0 that i floated a valve or 2 and they kissed a piston which makes sence to me. I have notice like i wrote before that if i get on ait a few times and the cylinder heat goes up the miss clears up, well i think that the vlave is bent just enought that its sealing itself under heat. I was towing a car home the other night and is coughed twice trought the intake comming off a stoplight, so that tells me right there that there has to be a valve issue. Im just gonna pull the heads and see what i find
