    • Q: 6speed swap with flex fuel kit  SubiLife7 months ago

      I have a 6speed swap in my car, will this kit work with my car?

        A:  This should work, but we cannot confirm fitment with swaps.

    • Q: Tune included?  MJ_05LGT1 year ago

      Hello, been interested in this kit since it first came out. I have the AccessPort and stage 4 (or something) build (hybrid Cherry turbo; forged pistons; decked head; balanced rods/crank; 3" Cobb downpipe; catless up pipe; enlarged TMIC; Apex WS2 street cat-back and all tuned on the AccessPort.) A real sleeper! I presume it will need a re-tune. Is that included in the $1,000USD? It seems a bit pricey for a couple of hoses, sensors and connectors and 4 zip ties. I would imagine the cost is in the IP / tune. Thanks!

        A:  A tune is not included in this, you would need to contact your tuner to schedule one.

    • Q: AT LGT  LGTMATT2 years ago

      I drive an 07 AT LGT. What in this package is barring it from being used on an auto? I've been waiting on this kit for years lol.
      • 2 of 2 people found the following answer helpful

        A:  The strategy for the automatic transmission is more complex compared to the manual transmission software causing the fitment issue. Cobb has not released software as of yet to allow this kit to work with the Auto LGT although they are currently in development of compatible software.
