I got my wife's Forester XT Automatic (4EAT) dyno tuned at DynoComp Monday. She has the following Mods:
Forced Air Technologies XT 3" Turboback (with Cat)
VF39 (Ceramic coated hot side)
STi Up-Pipe
Walbro Fuel Pump
Panel Filter
ECUTek Tuning by DynoComp
Stock it put down roughly 150tq and 150hp. Here are the 3 stock pulls and boost/AFR:

After mods, but before ECUTek tuning it did 230tq (boost spike) and 196 hp. With no tuning/boost control it would spike to 18psi and quickly drop off to 7 psi. Here is that pull. Sorry no boost/AFR chart.

After tuning was done it did 258tq and 239hp running a solid 16 psi tapering down to 11 at redline. Here are the charts with the stock results for comparison:

Notes:
All runs were on 91 octane :( The stock FXT top-mount is heat soaking bad at these levels, we would lose about 10-15 HP on the top end if we did consecutive pulls.
I am quite happy picking up about 110tq and 90 hp across virtually the entire RPM range :)
Next mods: intercooler, and tranny cooler ;)
Regards,
Aaron
