I have 450cc injectors and was going to go the route of fuel pump, injectors, sfmu, megasquirt, ect. But now I'm thinking of just getting a portfueler, while on Hahn Racecrafts webpage a came acroos some prices. Is the portfueler mounting system everthing I need or will I also need to buy control module and the calibration program software or is that all included in the system?
