I've got a 2005 Stage 1 with a Stage 2 WGA and some other mods, which line should I be running to the WGA ? Black or Green ? Which has less spike ?

I adjusted the WGA today to 3 mm preload and it's still spiking to 18, maybe 19, hard to tell on the damn gauge. I'd like to keep the spike around 17 and hold 14-15.

Should I adjust the preload down further ?

I had a flatspot in the acceleration about 5000 RPM's before adjusting the WGA, that seems to be gone now (pulling timing maybe ).

I have a Turbo XS MBC to put on later once I get this WGA adjusted properly.

 

How much boost are you holding right now ? ... basically that's all to be concerned with while just running the WGA ... the MBC is what you're going to want to control the spike with.

 

It's holding 15-16 in 3rd, 4th and 5th.

 

If you are holding 15-16 I wouldn't mess with the WGA , just hook up the MBC and use that to bring the spike where you want it.

 

set the wga to about 12-13psi off the green line then bring the boost up the rest of the way with the mbc. that will give you the least amount of ptb and spike.
