no picture vince.
and i'm not sure if it's because i was tuned on a DD instead of a DJ but 4th and 5th were close enough together that i couldn't tell the difference on mine.
I guess if it's inertia based like a DJ then the gearing of the car would determine the load on the engine where as a DD is a load based dyno so it can keep the load constant. In that case you would have a faster spool on the DJ when using a higher gear due to the increased load, correct?

^^^ Yes sir... I typically tune in 4th and then verify in 5th gear. I will be doing more testing as we just acquired a Mustang dyno so i will be able to do true Mustang vs Dynojet comparisons...
Also the pic hosting was giving me issues so i just added a link..

Here's a pic of a gasket from one of the hot pipes. Looks like a leak. I replaced that gasket and retightened all the bolts. i was able to get 3/4 to a full turn on every bolt i touched including the 4 bolts on the t4 flange and the 3 bolts at the end of each header. It definitely seems to respond better but it was hard to tell because when i took it out for a test drive, it was like 40 degrees out and i was seeing 11.3 psi instead of 10 like i usually do. I also saw my afr's go into the low 12's which i never saw before. Normally i always saw 11-11.4.

It is always a good idea to re-torque down the hot side once or twice after you heat cycle it a bunch. Certain things like to warp, seat or straighten. Sometimes this causes leaks like the one you just found. Good find and best of luck! I hope it fixes it!
esp with the turbo i love
