how would you have to pull the power steering res.? i didnt have to do that i used a long extension and it went right to the bolt...i didnt have to pull anything except 2 nuts off and i was done......and for some reason,,,i got my car back from carmax this morning from my finaly warantee work being done before it ran out,,,i pulled my chip prior cause i didnt want it to void my warantee,and the pcm saved all the info...its the same as if the chip was in there,,,its really weird,,even my buddy that did the chip for me said he hasnt ever heard of it doing that before
