By the way, I had my first Cobra dyno tuned and it ran great.

But, I took it to a guy who specializes in tuning these cars for max driveability. He was manually tuning a 12 cylinder carbed 60's Lambo when I first approached him. He changed my distributor advance curve and springs, experimented with timing, fooled with the carb and did it all by ear and seat of the pants feel and by checking the plugs.

Felt like he had added 50 horses after he was through. Jumped like a scalded cat when you nailed the throttle and would cruise all day at 2000 rpm. So, my point is, instruments give you a starting point, but every engine is different and it just needs an experienced tuner to get the most out of it. Sometimes you need to get rid of the instruments and do what your engine likes. They all have their idiosyncracys (sp?) and it's our job to put them in their happy place.

And yes, it is voodoo!
