smoke

What temp are you running at? I find that I get a lot of smoke at the low end, but less when going fast.

Harder to see the smoke at high speed...

Possibly a little lean on top. It's hard to say without seeing it. When you temp it are you bringing it in right after a run and temping right away or waiting a few seconds? WHat's the temp?

Yo Yo.... do you have a temp gun?

Put your car on a stand, and see how much smoke comes out at different throttle intervals... Then you'll have your answer and you can tune from there.

What was the resolution to this? Was it running lean at the top-end?

Have you done the pinch test? If it instantly dies or dies before 3 seconds it is lean. So richen the LSN.

But inititally you want to tune the HSN, then the LSN and then you may have to adjust the idle.

But for the HSN, when you are tuning for high speed, does it want to die when you give it Full throttle? If it does, more than likely the HSN is too lean so richen her up. There is a fine line between going the fastest and blowing up the engine. Running the engine too lean will reduce the life of it.

Once you have the HSN tuned right then adjust the LSN to get the best Acceleration of the line. The pinch test is a great method to help you figure out if your LSN is out of tune.
