I'v had my tps unplugged for years. From what I had read on the rat forum lots of folks were running the procom with the tps disconnected with good results. Those running aftermarket carbs generally don't have access to a tps anyway. I had disconnected mine because of problems with my bike cuting off when it hit the rev limiter. Lately my bike had been missing on start up and tach acting up so I figured the cdi was getting ready to go hence my purchase of the procom unit. I'v only put a 100 miles on it with the procom so far. Its seems to run as well with no real issues except for a little longer warm up time.
