I started out buying a Accel DFI and after playing with the (now) Speed Pro system quickly sold the DFI for the Speed Pro system.

IMOP the Speed Pro system is much more user friendly and with the wide band o2 sensor gives good feed back for tuning. I think it has been posted and agree that your car can be made as fast with either system but you can get there faster and much easier with the Speed Pro system.

Good Luck
