wanted to see if someone could take a look at my tune and give some pointers, I had it dyno tuned by a local shop and it has some issues and I don't really want to take it back to them, it starts and idles fine but has a big stumble if you try to ease into the gas from a street light or dead stop or if you try and snap the throttle it stumbles, it seems to run fine and has good power when driving down the road, and flooring it when your moving, it also takes forever to shift from first to second
details on it,
