New to turbo cars so don't know that much about the tuning and behaviors down to a science. But I know evo x run rich stock and on a ww u see it all over then back. Yesterday just installed a Invida Q300 and started it up and black smoke not blue. Also while driving, mostly in high rpms. Is this a big problem? And how could i fix this, and how much will it cost?

 

Pretty normal A tune would help also.

 

Definitely normal since like you mentioned they run very rich from the factory. I'm assuming you're not tuned. When you throw on some more parts, go ahead and get yourself a tune, and it should help with some of that black smoke.

 

i had smoke but it wasn't excessive. how bad is yours?

 

i don't have a tune yet, would a accessport do the job? and it noticeable while accelerating on the high way and ect.

 

I'm assuming you mean accessport, but actually you'll probably still experience some smoke with that as well. The OTS maps are known to also run rich as well. Your best bet is a protune.

 

Passport!!! I was thinking what good is a radar detector going to do??? Classic!!!

 

You will still get a fair amount of smoke in the lower rpm's if you roll into it in say 3rd even with a protune. I have a test pipe which just makes it worse. Theses car's are just very sooty. I got some nice fireballs from mine on the dyno on my 93 protune and there was a noticeable cloud of smoke when on the gas. This was with 11.7-11.8 on the wideband at WOT.

 

wow sorry fail on my part... but ill check it out and see how much ill nee to save, but the cars already put away for winter so ill have to tune it when spring roles around thanks guys
