losin my hp

Does anyone know if your knock sensor will affect overall hp...i put on a y-pipe, weapon r intake, 2.5" exhaust....and it isnt any faster....if any1 has any info it would be appreciated

Yeah it does. The computer i think goes in a retart mode (Safe mode) from 190HP to 160HP. Thats what i heard.

yea... change that shit.... kinda expensive though for a small thing but that's your problem... easy change...
