Dyno results are in...unfortunately they are less than impressive :( Charts coming soon.

I picked up 3whp but lost 3 wtq (peak). Above 6,800 RPM power is noticeably increased, but that's about it. Boost stayed the same, but AFR's did go a bit richer so more power will be had once it's leaned out a bit again. It also lost a bit of spool which seems odd, but Calvin (tuner) thinks he can get that back with MIVEC tuning.

Next up is the intake manifold and throttle body, might do these tomorrow and see if I can get it for a retune sometime this week or next weekend.

how much richer did it get? I'm excited to see the sheets once you get it actually tuned for both mani's.

Went from mid 11's to high 10's AFR.

After changing the WRX's oil, dealing with an oil leak, and cleaning it's Perrin air filter today I decided to get lazy and not start on the IM/TB job. Instead I decided to wash both cars, buy a case of Throwback Dew, and now just relaxing :)

Are you still on a stock turbo? Sometimes freer flowing exhaust manifolds actually hurt the spool on turbos. Just a thought.

I bet if you lean it out to get it to the same AFR you were at before, you'll see some gains.
