Get EFI from a reputable tuner...................................Not some guy that is close to you...................Idaho Rob at ATP has an autocal now that makes EFI very easy to do yourself, check it out.
i live on the east coast, went from ppe hot+2 to efi live tuned by epr and its so much better. trent is great to work with and makes changes to your tune as your needs progress.
banks will work fine if you dont wanna make huge power. like someone else said if you go with efi live make sure its from someone reputable and you always get what you pay for.
