Who is the quack doing the tuning? I wouldn't trust him with your truck anymore. Anyone who leans it out to that extent while in boost "to make a clean run" is not a tuner. Obviously there is an issue somewhere if it won't pull clean. Instead of putting your truck in a dangerous position to get a horsepower number, he should have tuned it correctly and figured out what was happening.
Sorry to be blunt but that is pretty shitty he would do that to someone else's vehicle

I have a gauge for that

It would be helpful to see what the o2 sensors are doing during boost. Its the easiest way to identify misfires, which is what it sounds like.
Lean is mean, until it blows up!
Close the plug gap to 0.020" and check to make sure a plug wire is not touching a hot pipe, even a little bit. No matter how much insulation you put on it the wire will burn through.

Like others have said, don't let him run the AFR that high, it needs to be richer. Did you do a compression check? Do the basics before you go back for tuning, compression check, plug gap, etc. What valve springs are you running? If it were me, I would get it running good at 12 PSI before I turned the boost up.

This... What plugs are in it and what is the gap? Dont ever go back to that tuner, anyone that leans it out that much with boost needs another job. You will be lucky if he didnt jack up your motor. Forget the saying lean is mean with boost. Boost likes fuel, at that boost level get your afr into the low 11's and be careful with timing if only running 93.

Could also be the plug wires too. I wouldn't try swapping out coils, they are rarely the problem.
You need to take your truck somewhere else. Anyone that would run that high of an AF just to get a clean run is not who you want working on your truck. He might have damaged something already, but don't get worried yet. from the sounds of it you need to get your tune situated before you start looking at mechanical parts.
Where are you located? I'm sure there is someone here on the board that can give you a good reference for a tuner. My buddy that owns a shop could send you a tune through the mail that will work too.

What scale is your wideband calibrated to? I thought you said you were running e85... if so wouldn't the wideband be off if it was based on traditional gasoline?

Hey guys. Just thought I'd go ahead and dig up this old thread lol. Ended up buying HP Tuners and reading everything I could find about tuning... Had to start from scratch and make my own tune file for the truck. Took a bit since this was the first vehicle I've ever tuned, but the ol girl has been running like a top for the last 2.5-3 years. Motor is fine, but I've been having trouble keeping a tranny in it. It's an 80e, but it's just a stock one with an HD2 shift kit.

sweet man, nice to hear!!! So what was the problem with the low power it made with the 7675 turbo after you got the cam situated?
