The CJ, for the majority that I have seen, didn't lose tq down low and made numbers from a little after mid range and up in the higher rpms. I would say it's definitely a good starting point. The lt's and other will only compliment it, as in more rwhp just like Brenspeed mentioned.
I have the Boss 302 setup and ported my TB and with the right tune, I didn't feel a loss down low in torque. She feels like she'll still move out. When I go WOT, around 5K rpms, she screams up to top. I haven't put her on the dyno, which is weird for me, but I'd rather see what the track improvements will be now. But hopefully I can port it before the next track outing and with some DR's.
