Just picked up my car from them yesterday. It is lightly moded, and I was running a old TXS Unichip (Stage 2 Maps). They threw in a cobb AP and did a custom tune, at 1st on my way back to tacoma, it spooled up like stock, I actually thought I lost performance. The Unichip would allow the turbo to spool to peak faster (so, it seemed), but would hesitate, almost like the fuel cut kicked in momentarily. The cobb and custom feels very much like stock until you hit 4500rpm, then there is no mistaking the advantages of thier work. I got better fuel efficiency also!!!
