any of the "aftermarket chips" made specific for your injector size, but Turbo Tweak / Erics are recommended.

I would also recommend the Extender Chip. I have run this chip with the stock turbo and 60 lb injectors and now with this new setup and the car runs awesome. With the low timing, I run 20-21 psi all day on 93 octane with the TC unlocked, pass emissions & get zero knock.
