soundengineer, LS1's don't have a choke since they are fuel injected. This function is performed with firmware in the PCM by simply injecting more fuel when the engine is cold.
badtoys, the surging you have could be due to an aftermarket cam; you need to list your mods for the best help on this board. PCM tuning may be needed if the surging is due to mods. Oh BTW, TB bypass will not cause this.
