Is this a Marauder or a CV? Numbers seem low for a MM with mods. I thought a stock MM was putting 240ish rwhp down.
 
A/F looks way of! If Iam seeing rt it said 13.9 or something?? should be around 11.5 Thats the 1st problem You wanna get fixed.
 
Don't panic dyno could be screwed up. Apparently it happens. If looking for a local tuner, mustang shops are the best bet.

Oh and overdrive needs to be off. Won't get an accurate read otherwise. If he didn't ask where the button was probably didn't shut it off.

Stock numbers on a humming bone stock engine/tune are 230-240rwhp and 270-290rwtq Just did mine for the first time few months ago.

the overdrive was off and the run start after 88mph so the trans won't shift to 2nd gear and this roll was in 3rd gear ..
 
I have similar mods - JLT air filter/intake, 180 degree stat but I use the xp103 plugs - one step colder heat range.

When I had my last dyno tune my A/F ratio ran a steady 12.0 through the pull and gave 269 RWHP & 294 F/P RWTQ.

Bone stock is 230-240rwhp and 245-255tq. TQ that high on a bone stock car is because of an improper reading, shift spike or 2nd gear run.

That's what I was thinking the problem was as well, another reason why the A/F could be off.
