Everyone of us needs to either do this or have it done if your not comfortable doing it. It's looking like its just that simple. I wouldn't trust any of them to be spot on.

I never thought gap would matter much under no load or light load conditions (idle). I guess I thought wrong.

Just got done checking mine, all 6 seemed to be "close" to .035. I made them all the same (didn't take much) and its all back together. Took a little over an hour, partly due to losing a socket in the Bermuda triangle .

Just a brief idle in the driveway seemed smoother, but I imagine that was just me and the fact the 99% humidity may have started to mess with my thought process. We will see if anything changes, though the change was very minimal for each so I am not counting on much.

Yeah I'm checking mine tomorrow. I have an '11 Eco with about 15,500ish miles makes me wonder if they r burning to hot and the gap is widening. Maybe need a better plug. Or I could be wrong I'll also post my findings tomorrow night

I thought the same. I figured the only improvement should be high load and boost. Guess I was wrong.

I think I am going to try this tomorrow.

What size spark plug socket is it?

Whats the consensus on the gap for a 87 perf./tow tune with the possibility of also using a 87 economy and 93 perf./tow tune?

I used a 5/8" plug socket. 8mm to remove the coils.
I think some of the guys with tunes are going down to 0.030
