Hello first off new to tuning LS stuff.. I have a turbo 5.3/th400 combo with summit turbo cam, decapped injectors and s475 turbo. 2bar OS running SD.. Been doing a lot research and have created a base tune to get the truck running, idles decent, cruises ok and gets into boost fine. But when coming off light throttle back the truck stumbles for a second and dies sometimes.. Can anyone point me in the direction to try and fix this.. Thanks!
