I know, once it gets cooler it will crack 400 and the TQ should move up too.

Yeah, a company named BMR has a AWD dyno out here. However finding out the HP with weight and MPH is pretty close too. It takes X amount of HP to move X amount of weight at 111 mph in a quarter mile.
If you use this.......calculator it is pretty accurate. http://www.wallaceracing.com/et-hp-mph.php
I used 111 mph and 4700 lbs= 495 hp - 20 percent for drive train lose comes out to 396 hp to the tires.......Mine made 391 hp...so.

No problem. Dyno's are only a tool IMO. Weight x Speed have always been king.

I understand, if I only had a decent way to time a quarter. I can kind of guess.

3bar, colder plugs, 170 Stat and an awesome Unleashed 93 tune. First revision so far. Want more but wife is worried about warranty on a '15 and with only 33k miles.

Been DD'ing the SHO for the past 3 weeks. GTI is getting worked on. I took the SHO to Cali a couple of times, ect. During the second trip, I started getting over active BOV's. Mine are vented to atmosphere, (maybe re-vent them back to the stock locations, I am the fence) so they are very noticeable. Very light throttle they are doing their song and dance. I chatted with Brad and he told me log it. Took me way too long to get the logs to him (my fault).
Friday night I took the BOV's off to check the o rings and they were good. I had the cover off and everything and did a once over of the top end. I went out and data logged the car and sent them to Brad late Friday night. I looked that the logs and noticed there was a difference in tip boost and MAP boost pressures. I was seeing 29 psi at the turbos, but only the commanded 18 psi at the MAP sensor. I didn't think much of it at the time, being up for 20 hours didn't help this. In hind sight, I know better.
I ended up going to the track Saturday afternoon/night and ended up running a PB. The car was getting it in the 8th mile, but just didn't seem right on the big end. It has run as fast as 112 in 1/4. It only ran 108.98 as the fasted pass that night. Packed it up disappointed because I thought she would run faster with it being way colder, way better DA, and a way better 60 foot. I know the 60 foot can affect MPH, however I didn't think 4 to 5 mph.
On the way home Brad literally emails me and says, "DON'T DRIVE THE CAR HARD!" OOPS. He could see in the logs that something wrong and told me to check all of my boost reference hoses. He also saw the difference in boost.
Sure enough he was correct. I got home and yanked the cover, and there she was. A hose was detached. Why any line that sees boost that isn't properly secured (hose clamp, spring clamp, zip tie, bubble gum, super glue, Ford was stupid about this) is beyond me. I posted pictures. Long story short, the turbos were running away (over boosting). The computer sees this and actually closes the throttle to limit boost into the motor (Ford was smart about that). I fixed the line and now she is back to normal and now has the big end rush again.
At the track with the boost reference line issue the car was getting all the boost out off the launch. The computer saw this and started closing the throttle during the pass, so....maybe in January we will see a faster pass.
Long story short car went faster (not at 100%), check your boost reference line (clamp it down), and SENT IT!
Also my SHO at full weight (no weight reduction) with me in it (240 lbs) and a quarter tank of gas weighs 4560 lbs. So 4320 by herself.

You're getting there! Can't wait to see what it runs when it's running 100%! And dang, SHO's are lighter than an MKS by a little bit. IIRC, mine was 4670 with me in it (I was 170 at the time).

It seems each time I go to the track it keeps getting faster, with more seat time she will keep riding.
