You know what who really cares what the dyno says? When I was big into dynoing my car it went the slowest. Now I tune the car on the street and really have no idea how much rwhp its making but I can tell you how many cubic foot of air it uses, A/F and track times. Take that beast to the track, its gonna fly.

Looked like you torque peaked a little early. I would retard that cam 4 degs. That will help take advantage of those high flowing heads and intake in the higher rpms.. You will pick up alot more top end that way. It may also smooth out your torque curve some...The 4.10s will also eat some HP..

pdd,

Does your cam have 4 degrees of advance??? I thought you were running +2???

I am really interested in that cam and had planned on trying it in a few weeks... but maybe at 113lsa +1...

Yes, typically if you reduce the advance you "push" the efficiency higher in the RPM range.

I am torn.. should I risk my peak HP for a little more TQ by going to a 113lsa or add a point or two of advance...

When you go to WOT from a low rpm does the car seem flat and then a big jump of power???
