Now, when you say your 'old' boss...is that because he's elderly or he's not your boss anymore? j/k

That is what I hate about Wheatley and Nelson. You can bash Wait4me all you want, but even he doesn't lock his tunes.

I've got a file from my original tuned truck that I found to be somewhat respectable considering back then it was 1/3 the price of a nelson tune.

I'm not saying he can't tune period. Just sayin the ones i have seen including the one that came on the rc i bought was at least 85% junk.
Of course i've only seen a handful of em so i can't say nothing from him is of any quality.

U shudn't need to worry about temps (IAT or underhood). I have the old Dynatech's too and shuda got the ceramic coated. I ended up wrapping mine, but only the first 12" from the heads. If u wrap them all the way, ur likely to crack them - especially with ur winters. I wrapped mine to get temps down and stop burning wires. R/

If I were you, first thing would be get Nelson to send you a PCM tuned for the addition of your headers and get him to disable your rear O2s. Then you can see where you stand. I would not want to have just the light turned off, then you wouldn't know if the problem is fixed until you pull codes again, or try to get an inspection.

Yes, that is the plan now.

Its hard to think about the next upgrade when you keep looking at that bleeping engine trouble light.
