Couple questions about the gtx. Currently has the Skuce manifold and Tial 38 wg.

Under boost, only when warm, I get a whining sound. Boost gauge doesn't seem to change at all. I've checked clamps and couplers, doesn't seem to leak.

Could it be a boost leak somewhere? Does an ext wg make any sounds under boost?

2nd, under boost my afr's drop to the 10's. Plugs and wires are new. Plugs are heat range 7, iridium.

Ideas?

does it whine similar to a supercharger? my BP does this too

as for A/F you have a wideband or narrow ? being a single wire o2 sensor ill assume narrow? more than likely a dieing or dead O2 sensor

Innovate wideband. New in May. I think it works properly, I'm just running rich

the only thing i know of that would increase the fuel that much would be the o2 if the ecu still thinks its cold ..... if it was a temp sensor it would run like a bag of potatoes .

you haven't tried checking the ign. timing have you?

could try timing it to level out the A/F , other than that i couldn't tell you with out physically seeing it ( :lol: i'd skip work to go see that thing again :hail: )
