looking for some advice!! i just bought a 2012 jk with the 6 speed manual trans. so far i love it!!! its everything i expected it to be. but the is a good half second lag from when i push the throttle to when the engine revs. is there anything i could do to have better throttle response? i have looked into it and came across the sprint booster. good? bad? any thoughts? truck has 500 miles on it and would not like void any factory warranty. thanks for information
