When adjusting the low on the arc2 to take away fuel from the curve you compromise the idle. thats why I told him to lower FP. John. Your car is just about maxed out in it's current configuration.Unless you run more boost.

I would not go 72lb unless you use VR maf or standalone. 72lb injectors drive the duty cycle to low. They perform erratic and overfuel at idle. This can lead to engine failure. It will wash the oil off of the cylinders and cause scoring.

Jimbo, Thanks again for the advice, which I'll heed. John at Vitesse is away for a couple of weeks and I was getting impatient. Actually the car is running well, with just some blue smoke on startup. Did it do that when you owned it? Also I'd appreciate anything you can tell me about the turbo and why I should replace it. The spool-up isn't bad and it holds 18lbs to the redline.

Car did not smoke when i owned it. Sorry it did until I installed a restrictor on the oil feed of the turbo. Turbonetics turbos are built like crap. The turbo compressor might be good for more hp but the stage 3 turbine will limit it's full potential.

Jimbo, thanks one more time. ATP always includes an oil restrictor on the VW setups. It only smokes on startup. I'll pull the IC tubes to see if its from the turbo. I've seem a lot of posts and guess it could be oil dripping down the guides. No smoke on deceleration though. I've really got to get a handle on the turbos you guys are using on the 951s

I replaced the axle today and will try to do some more testing over the weekend. We've got rain on Sat, but clearing on Sun. It looks like the NE is due for a blizzard.
