Common problem I see every day , car can be nmade to idle and drive properly BUT it will always be down on midrange , from 6500rpm it will be stronger than a mild cam but it would need all the componentary matched to be effective from 6-7k where it will make its power.
It will make less power than a stocker up to the 6000 rpm point so not surprisong your bolt on car nearly eats it
Poor matching of components just makes a dog no matter how you try to look at it.
Too true. This is what I need to get him to understand. A large cam only is not the best option for his setup, either smaller cam or the goodies needed to compliment the cam he has.

Had the same thing myself a couple of weeks ago fitted a cam to a vyls1 and it idled like a prostocker but made15hp over stock.far less midrange .Was pulling 90kpa at wot at 5000rpm.Had me stumped as wasnt supposed to be a big cam.Tried in vane to tune it. Gave up pulled the cam and replaced it with the SAME cam part number.Fired it up nice cammy idle and 35more hp after some investigating the cam was incorrectly ground and was never gunna fly on a stock ls1. Right combo of parts is everything.
Also correctly fitted is very important to the process , what you describe above is just wacking a cam in and installing dot to dot which rarely works , any cam that is fitted needs to be dialed in with a degree wheel , the offset on the cam would have been discovered at that stage.
Well, I've just managed to piss my mate off even more than he was. Managed to squeeze some more HP out of the car, his 20hp advantage has just turned into a 6hp deficite.

The scariest part is he paid for this tune. You have to wonder what else is out there from this tuner.
