impressive.. going to the track soon?

 

Can anyone tell me why some dyno sheets (like this one) have a "jumpy" curve rather than the "smooth" curve? Is it tire spin, dyno calibration, or a tune problem? I see it sometimes, and have always wondered.

 

I thought it was dependant on the smoothing but as you can see in the top right corner, this one is already on level 5 and iirc thats as high as it goes so there must be other factors.

 

Found this vid on youtube today, 2011 5.3L with a whipple 2.3L:

Pushin on the lean side. Still just at 6 psi?

 

I am hoping to go to the track next time it is opn here. It will be a few weeks.

Yea I am still pushing only 6psi-its because I only have the 3.625 pulley. As far as the lean side I was told it should be right around 11.6afr and i thing it is pretty close.

Here are some videos.

Does anyone know if whipple has the IAT sensor relocated to inside the manifold. Or is it still with the mass air flow sensor.

 

should be able to check the wiring on the MAF and see if all the wires are still there

that is a good thought though, if it werent in the manifold then it probably should be

 

Vortech's tune was 10.8 with the 3.8 pulley. Plugs were super sooty and so was my tailpipe. I swapped to the 3.65 and it cleaned everything up very nice, like they knew I would or something.

I need to get a vid of mine up, Ill try this weekend to get some good ones.

 

Problem with that is the MAF sensor had all of the wires in the back of it. Once I started to pull the wire loom back I noticed that he had cut the wires instead of pulling them out of the harness. I was also ablw to get in contact with whipple and have them send me a copy of the installation instructions. Very quick service response on thier emails. Also very willing to help. I am gald I went with the whipple set-up because it seems you hear about the bad service stories most of the time.
