Looking at trans kits and cant decide to go with the 3 or 4 SC. For starters i plan on update my VA 110 to the 230 and then switching to the TTS Powerloader 3 extreme when available. I tow heavy quite a bit and i would be doing several truck pulls and just a little dragging. I dont plan on going to N2O or LP so i thought the stage 3 would be fine. I'm looking at max hp to ever be 500. I plan on installing this kit myself as well. Any input would be great from u guys who have run these items before.
