Prochargers..... I am installing a set on a twin 350 mag mpi motor now, should have some numbers in early march.

Does that mean your not selling it anymore? though I just say a post saying you were?

I don't care either way. I have the boat and the prochargers, gauges, props etc. I love the boat and it could not be replaced with anything else for the money I would sell it for. The chargers are still boxed up (since christmas). I am finishing up a 57 vette job before I tear into the boat. Hopefully in the next couple weeks. We have been looking at guns and hustlers here lately.

I made more calls this afternoon and can't get a straight answer about remapping a stock ECM for a 350 mag mpi as mentioned above. Does anyone have any suggestions?

Tyler Crockett in Michigan does ECU upgrades for 454/502mpi's maybe he does something for the 350s.....just a thought...............doug

Talked to my dealer today and they called mercury. Nothing is offered from merc for reprogramming. Aftermarket would be the only option.

How do you get ahold of Tyler Crockett in Michigan? Thanks

I put a 5psi Procharger on my 99 350 Mag last fall. So far I picked up 13mph but ran out of warm weather before I finished tuning. Sent the ECU off to ASM to remove the rev limiter and set up for a 2 bar map sensor. Now just waiting on the weather.

What boat? what speeds prior to installation? what prop befor an after? sounds impressive.

It's a 22 1/2' Crownline bow rider. Ran just over 50 mph gps with a 19p Mirage Plus and now run a 23p at just over 63. Still had some issuse with timing and rev limitter last time out, should be able to get 65mph with a little more tuning. I have plans for manifolds and higher boost this summer, shooting for 70mph.
