Default Cheap 496 mag upgrades (375hp)

okay, my boats too slow, I have no "extra" money and I want to go faster.
What do I do?
More specifically can I reflash the ecm on this engine?
What would I gain?
Is a cam a good idea with the reflash?
Any other inexpensive upgrade ideas?
Thanks everyone!
Joe

The cheapest gains will be from prop work. Beyond that, there are no cheap upgrades that will show significant gains. If you can find a take-out 496 MAG HO cam and ECU, you can pick up 50 HP. That would be your next cheapest upgrade IMO.

The difference between a mag and an HO is the cam and I think the ecm program is a little different.

50 hp with an HO cam swap, a little more with an aftermarket.

10-15 hp in porting your stock exhaust.

I wouldnt waste the money on an ecm reflash only.

There is no cheap hp.

Just my .02

Just buy the Raylar 103 cam and roller rockers and have him re-flash the ecu while you are at it. Probably $1500 for all of it. No sense in using/finding a HO cam.

Joe, respectfully, leave it alone. Enjoy it. Maintain it and have fun.

I'm being sincere.

Good luck!

Buy a lottery ticket and enjoy what you already have until you buy the right ticket !!!!!!!! If it's not broke don't fix it.

This is my best bet I know, but it looks like a new (used) boat is a little further away then I would like, oh and stock motors break too, this is #2 motor in a 4 year old boat, why I didn't upgrade during the swap is a looong sad story

What about selling the complete motor and buying / build another? You might be able to find a used 500HP or similar.

Just noticed what you are running for a boat . My buddy has one of them 260 Velocity's with a warmed up 525 efi in it . Fast and fun to drive , but not for the faint of heart. A cam , lifters and a ecm would be a quick and easy 50 hp but after that it starts to add up fast. good luck Jeff

Well I'm kind of in the same boat right now, but I have and HO. It is hard to put money in engine upgrades when your paying a boat payment and storage. Well like some of the other people said you will probably get the most bang for your buck with a lab prop. You can do a K&N filter that will add a little HP and you can install new headers that they say will add 40-50 HP. The headers are my next investment
