As far as playin on the street. With the mp8 off it never seemed to make much rp just messn around but now if I hit it it'll jump right up and maintain it. I dnt watch the rp guage much doin wot stuff because my truck gets a lil scary lol lifted on 37s and it'll still spin them all the way through 3rd and into 4th. I know if I hit it it used to drop down to 13k or so but now it doesn't seem to drop at all. Ill try and get my brother to watch it during sum pulls. Also b4 the arson with everything crankd up it took forever to get over 24k but now it jumps up over 26k. But remeber iam on stock injectors so it may do different on yalls trucks. Also on the truck I mentiond early. With those mods his RP hit 29k and through a code. He has a freak of a stock cp3. He put down 645 with it completely stock then added the arson and now his turbo is limiting him. Anything else? I get to rambling sorry lol
