I'm thinking about getting my ecu reflashed by TS...is it worth it? Any differences? Should I get the limited spec for the full spec? Anyone know the estimate gain from the reflash?

 

The auto ECU flash for 5.5 autos, especially if you have headers, does not seem to be worth it. Check out threads by Blubyu and juice on that. I would, and plan to go with the L Spec version and an Apexi SAFC II to adjust A/F ratios.

 

Save your money, in my opinion the reflash was a complete waste...again I am speaking form my experience with the headers and on an automatic. Results have differed on manauls. I would say go the route of the L-Spec with the S-AFC.
