COST: for DCT tune and potentially getting refused DCT warranty service: $125.00
2. Dinan: direct relationship with BMW (locations at BMW stealerships) extra warranty covering their modifications = No refusal to service your DCT Trans.
COST: for DCT tune and continued warranty service on DCT $300.00

Considering that the GTS tune is an OEM program for the same transmission in a M3 GTS and the Dinan is 3rd party and is not warrantied past 50k miles. That guy that doesn't warranty his work doesn't have to because he's programming something that has already been vetted and warrantied by the OEM.
Let it be known, if the Dinan program causes your transmission go tits up and BMW hears word of it, they're likely going to defer you to Dinan for the repair bill. Full transmission replacement on these things run north of 4 figures from the dealership and Dinan won't warranty them past the new factory 4yr/50,000 mile warranty.
The GTS tune is good to go with my CPO warranty. It costs less and I'll bet the differences between them aside from the obvious price delta is marginal at best.
