For those who've done this, is it ok to run the stock f37 programming with euro spec tq converter???

I don't have their turbo but do have their full torque eco tune. I have two TCM's. One has has F37 programming and the other has the pre f37 programming. For me each have their place. F37 with the later shift points works out better for me while towing out 3500# camper but for daily around town driving the Pre 37 gives better mileage. Reading your profile I suspect you do a lot of off roading and I don't think it would make any difference what tcm tune you have

If I were you I would wait and see how you like how it preforms
One member has sold his GDE programmed ECM and has gone back to one of the stock versions.
The big thing is you have the Euro TC

2mopar_diesels - I'm not sure I understand your question as the post title doesn't seem to relate to you original post. If the question is can you run a Euro torque converter with an F-37 programmed TCM I don't see any reason why not. You can run a non-Euro stock TC with pre-F37/post-F37/GDE TCM tune and the Euro TC is stronger so the answer seems obvious. If your question is can you run the GDE turbo without a new flash of the TCM I think the answer is yes but best check with Keith. To use the GDE turbo you need the new ECM flash which comes with the turbo. I did speak to Keith about running the GDE turbo with a stock post F-37 torque convertor and he STRONGLY advised against doing so.
