SI PT4000 locked vs unlocked results. On a mission to figure out some issues that my buddy is having with his car I dynoed mine as a comparison.
My mods are:
2001 WS6 A4
Homemade ram air kit,
lid w/k&N,
no MAF,
FAST 90/90 tb,
EWP,
pulley,
LT headers w/ ORY,
Magnaflow catback,
YANK PT4000
stock rear w/3.23s
and tuned by the best tuner in the world.
Pulls were made on MT Drag Radials (275/40/17) at 30 psi.
358.19 rwhp locked and 343.69 rwhp unlocked
On a side note, even though it losses 15 peak rwhp it gained 3mph in the 1/4 from just the converter swap.
The dyno was ( or always has) trouble with there rpm readings so graph is only RWHP by MPH. It's interesting though as I was turning the car to ~6100 everytime, so you can also see the loss of MPH from locked to unlocked.
