Andre34 Posted May 26 Share Posted May 26 Hey everyone, I’ve been trying to figure out how to get rid of this dip in my power curve. I found when the IMCC valve in the intake manifold changes state, my AFRs go very rich and I loose heaps of power and torque in the process. I’ve tried leaning out my fuel table and advancing spark at 4200rpm but it didn’t do much to help. Is there a trick I’m missing? It almost feels like there’s a parameter forcing fuel in when the IMCC changes state. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted May 29 Share Posted May 29 Is the valve physically moving? Run it up on the dyno and watch it to see if it actually moves. Quote Link to comment Share on other sites More sharing options...

I can see a big difference in power when I keep it open Quote Link to comment Share on other sites More sharing options...
BarraTuna Posted June 8 Share Posted June 8 What XR6? ? Is it a BTR? Look into torque restrictions maybe Quote Link to comment Share on other sites More sharing options...
