i agree with u on that also, and i wasnt saying dyno jumping is the way to go, i was saying the exact opposite, read my post again, wat i said was go back to the same dyno if u want to see wat differnece ur mods made..
as for the mph, well my car made 261rwkw and i hit 118mph at the creek, so i guess it sounds about right, considering it ran a 12.8 first time out and a shitty 2.3 60ft :
