I put two srt TBs on my car for 6 months and the computer will need remapping as it is too much air per degree of opening and it does indeed hickkup. That can be damaging when the engine shuts off for .1 seconds and restarts. Really annoying and I finally decided that since I was not going to play with programming, to go back to one TB. Could help, cost and time not worth.
