Hi there,
New member here and a complete noobie here, i have a single cab silverado with a 6.2 denali engine.
Mods are :
Engine : ls3 pistons, ported heads and ported manifold, ls3 valves, ls7 lifters, texas speed 226/236 117 cam, 660 springs and a caprice throttle body.
Trans : stock trans with a triple disc 300MM 2400-2700 stall converter.
Issue is I'm completely lost with the trans tune, my tuner doesn't tune the transmission so if there is a base tune or something to help my tuner sort the transmission tune that would be helpful, sorry if my question is irrelevant because this is the first time doing an aftermarket upgrade on the transmission or dealing with tuning it. Thanks
