Today we did the AVO 30kW package on a customer car at the Melbourne, Australia shop. This car included the AVO 30KW package with a AVO Flex joint Up-pipe tuned on 95 octane. As you can see the boost pressure was not raised - so how did we make the power??
With the Subaru one of the biggest gains to be had is with a good Turbo-back exhaust system, as the stock system is quite restrictive. That OEM stock was holding the beast back due to the 6-8psi of back pressure that it has. The AVO TBE with a cast nickel-iron outlet with a wastegate splitter and AVOs 200 cell per inch High-flow metal-strain cat converter removes that back pressure, that is where we gained the power without upping the boost.
