You honestly can't go wrong with the nova P5 xlt . I was the worst engine tuner of all time I struggled and struggled with that freakiin Lodi 454 until I was fed up and bought myself a real motor. Now I have an engine that holds a tune an hauls some serious asssssss!!! I paid less than 200 for it new and I will buy another one when this one dies. It's the best engine for the money period. Get yourself a weeks 2058 or nova 9901 (or losi re12) for pipes. It's what has been recommended to me by a bunch of guys locally and here. Pm me if you have any questions regarding the P5
