I thought I'd contribute to this thread by posting our dyno results today
Here's my run.
Blue line is my baseline run, Milltek full exhaust including overpipe and cat-delete front pipe, stock ecu, stock intake with the snorkel delete (I didn't want to remove the bumper to reinstall the snorkel just for this). Pulled 152.05whp and 127.76tq, best run out of three.
Red line is with the Afe Takeda dry intake, Milltek full exhaust, Unichip EMS. Runs conducted on the same day. Best pull was 161.93whp and 134.78tq.
Here's the AFR with the Unichip and Takeda intake, this wasn't the best pull
Compared to stock ecu and stock intake AFR
These runs were on a Dynojet, on a very hot summer day, about 36-37C ambient temp, with the hood up. I would assume this was an advantage for the stock intake because without the snorkel, it was taking in fresh air from the fan. The Takeda's velocity stack leaves no gap, so it's not able to suck in any air from the fan.
And here's the run of my friend's car. His car is also MT like mine, same 100RON octane fuel, around 5,000km on the odo with an oil change recently (my odo is 3,100km and oil was changed at 1,300km) has the same Milltek full exhaust, but with Injen intake and Ecutek tuning. Best pull was 157.31whp and 134.29tq. Again, this was with the hood up, with the Injen taking in fresh air from the fan
