Congratulations you have just installed your turbo kit made by Weller Racing and Race Proven Motors!

If you setup your POD-300 display to display AFR and pressure, that works the best. The pressure will be your boost. 14 will be your non
boost display, so 15 would be 1 psi, 16 = 2 psi, and so on. We expect you to call us when the kit is installed to walk you through a
couple of checks before you scream it down the street. Example: make sure boost is set correctly to 6 psi (20 on display) / AFR is 12:1
or lower (richer) under boost. Don’t hesitate to call or email us!!!
Our kits are constantly in testing mode to stay ahead of the game. Currently, this kit has been tested and proven at 6 PSI running 110
octane race gas. We are currently testing this kit on 91 octane pump gas and will have settings for that soon. We strongly
recommend that you run race gas until we conclude our testing. Check back with us for details. We also program the factory ECU inhouse, which allows us to remove the top speed limiter and any other function you may need.
Call for details on this or with any questions you have with our products.
