Dyno for maximun gains

[female four]

I'm new here but would like to ask a very in depth question about tuning engines.

I'm curious and would like to know how many of the domestic tuners tune thier engine. Particularly in how they look at the dyno plot for actual gains instead of peak numbers.

I would like to know if you guys focus on power/area under the curve and the idea of having as flat of a torque curve as possible instead of peaky plot curves.

As already mentioned, I'm new to the field of domestics, mustang in particular. On imports, the focus is normally on flattening the torque curve as much as possible and maximizing the width/flatness of the torque curve powerband for optimal performace after the upshift. This provides lots of available torque (what available torque they have that is) after the upshift so the engine does not have to play catch up.

Most and many threads only refer to a good job well done and I would like to know more about the focus on tuning these engines properly.

Looking forward to a good discussion.

Well with 537 ft lb torque I don't worry to much about the curve! In this arena we have tons of torque compared to the "TUNER" world. Our torque curves tend to be fairly flat without having to tune to get them that way, therefore we concentrate on max torque as soon as possible. At least I do.

Yes our main goal is to keep them as smooth as posible and hold them as long as posible

I want my torque to be as high as possible and my hp to match it. When I got my car tuned last week, we looked the entire graph over to see increases not just at peak but at other rpm increments. While my hp jumped by 54 at peak, it jumped 62 rwhp in other places at different rpms. The torque did the same thing, jumped 30 at peak but over 40 ft lbs in other places on the graph. Peak isn't any good if everything else stays as it was originally. I like to see gains all across the board. Of course, this was on my piddly little naturally aspirated 5.0 Cobra. Check sig for new Pro-Dyno numbers. That was the best Dan could do.... (Just kidding Dano )
