I have e-mailed them and seems like a good investment. But they did tell me to do a chip replacement last. Meaning do all for performance mods first and they'll set up your ECU to your mods for the perfect set up. Hope that helps.
Yeah I would go with that over the doing the chip frist. But IMO I would invest the money for the controller into a CAI, Cat-back, Headers, Gears, etc... But do what you want.
