“aprllcWe love the #30TFSI and we’ve spent quite some time figuring out how to add more power. We’ve tested expensive and inexpensive. We’ve tested too much, and too little. We’ve tested things others have done, and new things unseen. We’ve tested the good and the bad, and we think you’ll be pleased with what we have to offer.
Below is where the market was (Green – Pulley), where the market is (Blue - Dual pulley), and where APR is (Red - ‪#‎soon‬).
ETA: Boost season.
Price: TBD”
