Default Hesitation at WOT with SciVision (please read last post)

::UPDATED PICTURES FURTHER DOWN::

Hey guys,

Just picked up the last piece I needed today, my SFR turbo inlet pipe. It took a little work getting everything to fit just right, but I think I have it in a good orientation:




Please excuse the blurry pics, I couldn't get my flash to work any other way than putting it on night shot.

My only set back right now is I don't have anything to mount the bypass valve. Tomorrow I'll take care of that and get her running to! Finally!

-Darwin

Well it's all done and the difference is pretty apparent. The car acts more aggressive (altho that's probably just my mind) and the MAF really makes all the "turbo noises" come out even greater!

I know there is no MAF that is perfectly tuned out of the box out there but this one is a true plug and play in my opinion. I'm going on 3 years and 2 Calif smog test since install and still running well.

The more I look at your setup the more I'm beginning to like the cone filter setup. I know SFR did your custom turbo pipe. Would you mind sharing what it cost to have it made? I'm considering getting one to use during the winter months.

I'll shoot you a PM. It wasn't really a custom piece, as all I told him was I needed a 951 turbo inlet pipe and I had deleted the CV, and used a diverter valve. He knew exactly what to make and how to make it.

Ok guys, now I've had a chance to get out and play around with it a little, and I'm puzzled about something. When I go full out (no matter what gear) I get a small "hiccup" in power around 4500-5000 RPM. I don't really know what would cause this. The chips are mapped for my exact modifications, and I've double checked every vacuum line and connection I could think of that I touched in this process. I'm going to call Russell tomorrow and ask him, but in the mean time, anyone have an idea?

Something makes me think TPS, try getting the RPM that high without going 3/4+ throttle

Nope, it is oriented correctly. I quadruple checked that during re-assembly.

Hmm...is there any way to test a TPS?
