i was pretty much a full bolt on na setup with boss manifold stock 3.15 gears and complete rear suspension minus shocks and totally stock front end minus front sway bar, and the 5c worked well. people would tell me "we don't recommend the 5c" when boosted, and I thought there were just being up tight , but after about 2-2200 miles of driving boosted with the 5c I am about ready to swab back to the stock converter and put the 5c on the shelf till I figure out if I am going to be able to build the motor this winter to crank it up to about 850 rwhp or not. So I only have to pay for 1 adjustment and when the motor is out of the car it is easier to swap the converter. I also have 3.55 gears now which help max the trap rpm. So with 650 to the tire and the 5c and 3.55 gears the converter is just looooose. almost annoying to drive normal on the street like a civilized person. don't get me wrong it is nice stomping the gas if you can keep from not leaving the road. ultimately at my elevation a 2 or 3 c would be the hot ticket- I will probably go 2c and pulley down and lower my shift points 400 rpm to hold motor together, if I don't scrape enough cash together this winter and have to rock the stock short block one more summer. I didn't take in account for your elevation which definitely knocks down the power.
