The stumble I experience seems to be discussed quite a bit less. No problems with acceleration on my bone stock 09 5MT LGT.
The speed limits in my town are all 15mph and I struggle to find a way to cruise at low speeds without the MPG needle bouncing back and forth. I do feel the resulting jerkiness too. I assume it comes with e-throttle territory, but I have to think that a tune more sensitive to low speed input could help?
Thanks for the wisdom!
