 Towing and Tuner Chips
This week: New Goodyears, K&N filter, new upper/lower NAPA hoses, Gates thermostat, coolant flush, Hayden 5000 trans cooler, new ceramic brake pads, getting ready for the pull. Yeah, she's running better than ever.
Just came home with my 21' Outback TT, 4400lbs. Yep. Weighed it. Gotta tell you I was not impressed with the towing capacity of the Expy. Not that I had my expectations too high. I have no intentions of going over Wolf Creek Pass with this setup. I know the 4.6 just doesn't have the torque below 4000, and the suspension is kinda soft. But my real gripe is the shift points on the tranny. In 2, floored on flat ground, I could reach 65 easy, about 4000rpm, with little trouble. Ease up on the throttle into 3rd and 2500rmp, and she couldn't hold the speed. Speed drifted back to 57 or 58. Add more throttle and she shifts back down into 2.
All right, I admit, I am cheap and lazy. I really don't want to change the rear end if I can help it, although in my heart I know it is the most effective. And buying another TV(like a PSD) is not really an option right now.
My question is, have you ever heard of an aftermarket chip controlling the tranny shift points enough to keep the thing flying in 3 without lugging the engine, or should I just suck it up and re-gear the diff? And if I re-gear, does that screw up the performance due to the stock chip programming? |
