Have a lot of info from an installer but he has moved. Has anyone experimented with this vehicle?

Depends on what you need. I was told not to worry about the 02 sensors and use potentiometers to control the signal strength wires from the IAT and MAP/MAF to ECU and not to directly inject the gas directly in the PCV valve but go through the air intake (more of a filter).

Boltz...forgot to ask you how your cell is setup and how things are going for you. I made my cell a 8in. x 8in. stainless steel box with stainless plates but am trying to figure out what I'm going to use as spacers between the plates. Has to be able to withstand 170 degrees and the chemical reaction without breaking down...I'm stumped on that one.

I'm going to be using a 6x6 dry cell, 2 bubblers into the air intake. I don't know about NOT using enhancers for the o2 sensors. I plan on using a maf enhancer.

Sorry about the delay in posting, more family problems than I can deal with.
