I have a full Yosh system on my Rally and it made a difference. Hopefully next week my Stage 1 ECU and Airbox lid should get back to me from 550 Performance. Can you tell me what to expect in terms of difference i should expect when i fit them?
It’s not a major difference but it’s enough to notice. It definitely feels like it pulls harder and with the rev limiter lifted you can give it that bit more in each gear. Low down torque also felt better
I fitted the lid and the ecu at the same time but doing so made a difference. I went with the twin air because apart from having better flow, the replacement foam is cheaper than a replacement filter

Can you tell a difference in performance? Also, any feedback on the TwinAir filter?
