For my 2008 fleetwood with w22 chassis do I just get the ecm upgraded or do you do the tcm too? Also when I send back the old ecm do I get the refund? Thanks.

Btw my v10 tune you did on my other rv is awesome! ( Bryan, 06/20/2021 )

The 08 would just be an ECM upgrade as we don't tune the 6 speed Allison TCM . When we receive your old ECM we would refund the core charge .

Yes, we can tune for the upgraded camshaft.

Unfortunately, we are unable to tune the TCM on your truck.

Can this be used in a boat? ( Jerrod , 04/04/2021 )

We do not have any experience in tuning the 8.1L in a marine application.

I have a 2001 Kodiak 8.1 that was turned into propane I turned it back to gas there seems to be a code turned off fuel injectors from computer need new computer from when Truck was built before propane was installed ( David Burch, 03/22/2021 )

If you want to send your VIN, we can check to see if we have the proper calibrations on file to do this for you.
