Topic: 264 aftermarket Cams decreased power.

I bought aftermarket cams and replaced the blacktop cams. My last dyno was in September 2013 and I made 129kw and 183nm. I installed the cams I bought and have the car dyno tuned, I made 125kw and 175nm. I checked the timing markes and the compression. It's been seven months since the last dyno. But the tomei cams has higher lift and more duration I expected a slight increase in power at least. The duration on the dyno has increased too so therefore the drop in power is evident.
Your help will be much appreciated.

Maybe the dyno is inconsistent.

How does the car feel on the road?

Re: 264 aftermarket Cams decreased power.

You can't just drop cams in & expect power.
The exhaust cam must be dialled in with a vernier gear.
The timing needs to be set on the dyno.

Also,if the head hasn't been skimmed yet,have it skimmed or fit 2 X 7AFE head gaskets to bump up the compression.

Have the car retuned & you'll see a difference
