I would reach out to Vivian at quick tricks and Chris at TSD as well....The looney and SPD tunes are top shelf as well.
I have never had a tune before and I just ordered a looney today to put on the truck and it drives nice and makes a sh!t ton of power. I am asking her to tweak two minor things and I will be happy with this tune. I am also going to order an SPD tune from TSD as it seems to be the cats meow right now on this forum for all around power and drivability. I cant say enough about vivian and her customer service, I had my tune in an hour. I have heard chris is the same way , do bare in mind they are moving shops and should be back up and going soon if they are not already.
I know Matts SRL and SRL+ are topshelf too and I will most likely order an SRL+ at some point to try out .... I have heard his tunes are very linear and the drivability is really good.
Eric is one of the original tuners and his tunes, well....speak for themselves.
It is really more about what the truck likes not so much what you like.
Hope that helps.
