My experience is that any tune (accept the one that ONLY deletes the EGR CEL's) will require an upgraded TC, but you can drive around it for years of light duty, and from what some say, they didn't have any shudder with the stock TC and an Eco tune, but I sure did. It seems like some TC's are better than others, as I installed a new Hemi TC recently, and I still have light shudder under heavy acceleration around peak torque, but anti shudder additive may have cured it.
Not a bad way to go if you can swap the TC yourself. If you have to pay for all that labor it gets expensive. Updated pump is good insurance if it turns out that it doesn't already have one.
