will we be able to back out the mixture screw until its flush without trippin the CE light?

 

Yes back out screw and you get no CE light. The stock ECU will handle up to 11% adjustment for STFT (short term fuel trim) and as long as you don't exceed that you are fine. When at WOT due to the stock camshaft, intake manifold etc the engine will pretty much still know to put enough fuel for safe running (instead of being slightly too rich like most mitsubishi engines run you will be closer to a perfect setting and letting more air in. ) If all else fails just put it back to where it was previously.

 

Well I hope we'd all be running a(I do mean 1 and only 1) cat while we're street driving DIM.

 

...and I do hope that people do NOT try to run 14.7:1 at WOT because they thought it was best and BLOW UP their engines or melt some pistons. 14.7:1 is what you want ONLY at cruising and idling (and some light throttle acceleration) since you mostly drive in these modes but at WOT you still want a richer air/fuel mixture.

 

True enough. Run rich enough and you'll melt out your cat though. You place the happy medium for A/F at say 12:1 right for a turbo car that is?

 

I just removed all the seats, all interior plastic, all the windows, bonnet and trunk lid, and all the ground effects(left the doors because i like the little keyless entry thingy). that lightened it a little but the aerodynamics suck worse than before. That is ok though, i am going to kmart tonight and getting tarps to take all the places of those parts. ill post a pic when im finished.
