That is so close to the numbers I had it is scary. Where did you dyno that thing and what did you do for the ECU tune? Since you will have yours running before I get anything going can I have a ride? :D

Very impressive for such a "stock" engine!

I am happy with the numbers it came up with for basically a cam, valve springs and a ECU tune. Motor was 352hp stock, so a 117 hp improvment.
I had the dyno and ecu tune done at Swankee engines in Springfield, MN. They have been at Back to 50's and Car Craft with a display for sure two years. I will give you a ride Dave if mine is going before yours. The big hold up will be the cost of paint.

Wow! Those are some great numbers Brad. I think this shows how awesome these LS engines are. Just a cam and tune gets you 117 hp! Makes me wonder what HP numbers a person could get with just an ECU tune?

Those are very good numbers. What did you think of Swankee Engines? Was it a guy named Mark doing the tuning? I bought some parts from him a couple a years ago and he said he was their tuner. I bought the HP tuners software, but with the limited time I have to work with it, I debate if I should let someone else do it.

Steve,

Mark at Swankee did do the tuning. Seemed to know what he was doing. They are about as costly as TPIS to do a tune so if you have the software already I would play with that. Can you back load it with another motors tune thats kinda a similar to yours and adjust form there???? I know nothing about that stuff??

Steve, the guy who did the tune on my EFI system was having a blast doing it. He is a code writer and a motor head, he took the software and PC played with it and when we got to the dyno he was all over it. I took the closest base map to my set-up and he tuned from there, adding a fatter mixture from the start and then doing a fine tune. He did explain things that did go over my head at first then later I understood them. It is one of those "Now I understand it moments I get" when we got toward the end of the session at R&R. I can get ahold of him if you like he loved doing it and Ron at the Dyno liked working with him.
