Vpc help!!!!!!!!!

[spooledu1st]

Hey guys Im trying to help a freind out that is running a vpc in his supra. Im just trying to get an idea of what dose what so I can try to lean it out. The car is running pig rich and sputtering the gcc is all zeroed out. But I dont really know how to lean it out. If someone can point me in the right direction it would be very appriciated. THANKS ALOT

Err... if you don't know hoe yo lean a car out with a GCC and a VPC, you probably should not try to tune it.

You want less fuel, so you need to turn the knob somewhere less than zero.

I was hopping you would reply Kyle thank you. I just came back from a run and I have the gain at -12 still pig rich and all the gcc leaned out also. Fuel pressure is at 45psi with vacume connected. Egts are around 600c after turbo. I was think that I should try to lower fuel pressure a little more because the car is running a tad better. Could you tell me what op output dose on the vpc. Thank you again for your help.

That fuel pressure seems a little high, I would try turning it down.

Are you using a wideband or something for this? If you're just tuning blind, stop now.

i think the problem is you are on the wrong website. last time i checked this wasn't supratuners

Thanks for your help and I know this is not a supra site. I just never used a vpc and needed a little help. But figured it all out.
