New CV Performance Slide..drill or no drill

I have an 883 that I rebuilt with a CVP tuner kit and it runs like a champ. I have some pinging at WOT so I am moving up to a 180 main. Otherwise the only other issue is every once in a while if I blip the throttle to take of from a stop it pops through the carb and dies. My only thought was it may be running lean so move up to a 45 pilot, but then I thought about the slide as when I installed the tuner kit the slide was drilled out to more than 1/8". I don't have any real issues other than a bit of a touchy throttle but I bought a new slide through CV performance and I am wondering if I should drill out the new slide to 7/64. I thought maybe the new slide has a bigger opening so it didn't need to be drilled as the tuner kit says you don't need to drill out bigger bikes or new slides.
