A chip can't always help much if the cam simply isn't ground to make low-end power.
First of all, something to consider is how you actually drive the car. If you spend most of your time at redline, then fine. However, if the car is driven mostly in the lower 3/4 of the rpm range, with only an occaisional zing up to the red, then big lumpy cams are a waste of time.
One way around losing low end is to add an adjustable cam sprocket and advance the cam a few degrees. Not so much that it starts taking away from the top end, but enough to fill in the gap off idle.
For example, if a cam is ground to work from 3000-7000 rpm, and you shut off at redline anyways, then 2°-4° of advance will shift the powerband downwards.
Get some DSR 256's...they give you more top end and don't take away as much bottom end http://****************.com/smile/emthup.gif
Wrong, How can a less agressive cam lift and duration, give more top end? Get a 268 cam file and you'll be fine. If you get Schricks, they are ground in a way to incorporate the "swing boost effect" . This acts to aid cylinder filling, and preventing torque loss. That is the only difference between CATs and Schricks, besides the dollar difference. http://****************.com/smile/emthup.gif
