Yeah, in 94 the base 2.3L engine was rated at only 98 or 100 HP and 130 lb-ft, so not a lot of power for a 3,500-pound truck. Mine had a cap over the bed which added a bit of weight, and also unusually tall factory gearing which probably made it accelerate slower than most other Rangers. Even so, it was fine when driving in flat areas when not towing. I towed a few times with it and that’s when it could have used more power, especially in the Texas Hill Country that has steep grades. Anyway, my point is that small trucks like this Slate BEV can probably get by fine with 150~200 HP or less, which could help keep costs lower. Also, same amount of BEV HP often performs better than equal ICE rating, which should help too in real-world driving.
Cyanlabs has a tool that upgrade from 3.0 to 3.4 go to their website and download the application on your PC and then go through the information on your Sycn 3 system and it will create the package for a USB. You will need I think 16 GB at least.
