Installing Procharger and SM manifolds on 454 Mag ----- do I need to have computer reprogrammed ? If so, who should I send it to ?

Which computer do you have?

You probably have a base Procharger cal laying around.

Nice avatar. You coming to CH this weekend.

I would speak to Tyler Crocket . We can tune it but I'd need to put it on the dyno and I think Tyler's got a differnt way. Best of luck Sincerely Laz Mesa

I'm staying home this weekend. Lake Cumberland kicked my ass last week! Besides I don't want a 100mph Donzi sneakin' up on me!

I understand.

Now don't come back to CH without giving me a shout.

Its going to take 2 things to make it run right. First your going to have to buy a established base ecu reprogram re-flash from a guy like tyler crockett or precision marine then to really be right it will have to be tuned on the water. Once you have a base program the reason it will need to be reflashed is the programmers have to leave it fuel safe so the water tuning will let you fine tune it which is especially important to get the most gas mileage. If your combination is a common one (which it sounds like) you may be able to skip the on the water fine tuning BUT it will never be as good as a fine tuned one. Your options at that point will be to either have someone ride in your boat who is able to fine tune it or buy mefiburn and do it yourself. Do yourself a favor and throw the procharger fmu (fuel regulator) in the trash if it what comes with your blower. THe best thing there is to use a aeromotive efi regulator to hold base pressure then route the discharge from it to a second regulator like a bell/cartech rising rate fmu which will be boost referenced to take over under boost,Smitty
