Car: 2009 WRX
Dyno: Dyno Dynamics (TCF 1.02 based on weather station)
Fuel: 93 octane
Modifications:
-Full exhaust
-Forge BPV
-Stock TMIC (Changed to FMS TMIC) Before vs. after
Tune:
11.1 AFR
17psi peak with taper to 14psi (IDENTICAL in each tune)
Substantial AVCS tuning
History: We retuned this car on the stock TMIC to it's fine result below:
Original Graph vs. local mustang dyno tuner results (Which read identical to this baseline of 262):

Then the customer added a FMS TMIC (coated) and retuned:

Couple notes:
-Both tunes were locked in on Shootout mode so the dyno cannot be manipulated - temperature data is taken from the weather station. Both curves used were the highest repeatable gains during both dyno sessions.
-We ran a near identical boost curve at spool up and near redline - but tuning had to take place, as with any intercooler they REQUIRE tuning - most if not all I see will make LESS power bolted on then without.
-Let me repeat, the intercooler on by itself will not necessarily make power - tuning is needed.
-We ran the same identical fuel curve targets.
-Spool had improved.
-Power curve had improved.
-Timing targets were able to be adjusted to increase power based on IAT feedback and efficiency of removing the horrible stock unit. This is where most of the power comes from.
-It was 20 degrees cooler this day. Which can attribute to some power gain and skew the test results slightly for IATs.
-The small bump after peak torque was boost control related and fixed.
