Houston Tuner Reference Request

[JeffP-Z]

I am looking to have my Z retuned as I am adding new performance parts and would like to get some feedback regarding Z tuners in Houston. Originally, My 370z was tuned at ProSpeed with my Stillen Gen3 CAI and ARK DT-S cat back system. They seem to specialize more in Chevy, Mopar and Ford, although they seemingly did a great job on my tune. I am looking to get a dual map (93 and E85) and will be adding Berk Test Pipes, Injectors, and pissible the SpecialtyZ Flex Fuel kit. I have been doing business recently with SZRPro (Formerly HoustonZ) and have heard alot of local people at meets recommending Admin (TheAdministration) for tunes also. Please provide feedback on your experiences and any recommendations you may have so I can make sure I don't keep blowing money on new tunes from different places. Thanks guys.
