Coming home from my friends house last night I decided to get on it and in 2nd and 3rd gear at 4K my car cut out a bucked really bad! Mods to it are 2.76 upper, RAI, catted x-pipe, and custom dyno tune. Also I did the PPRV delete about 2 months ago. Could one of the hoses come loss at all? I'm going to change my plugs and today and go from there. Any other suggestions would be great! Thanks!
