Right now I’m leaning towards a Turbo Lamik TCU, initial cost outlay seems a little more than the other two I’ve researched but it has more of the features I'm looking for. It completely replaces the stock TCU in the trans and allows transbrake, bump, and even wiring in a "clutch" pedal to emulate a manual trans if wanted.
The SGA seems nice but you're limited to the stock TCU and it's functions, and you have to buy $500 of HPtuners stuff to tune it yourself. The 8HP90 would be ideal but there are guys in Australia and Europe that are running 800hp I6 motors in front of the smaller 8HP45s, so I think the 8HP70 will hold up fine for my power level.
