I have a d15b7 hf mani 14b turbo 440cc injectors and a vafc 2 for tuning. I know that a vafc 2 for tuning sucks but this is my question. i have my 1000 rpms at -39%air correction and my eninge idles fine the problem is its running really rich and it smokes like a light blackish smoke. If i lean it out anymore it wont fire in like 2 of the cylinders. I checked it all the injectors still are getting power the pulse is just slower of course to fire them less but they wont want to spray or they will spray alittle some times. Just wondering is this the best my vafc 2 is going to tune or is there somthing wrong with mine. thanks

 

also when i start my car when its cooled it will idle up and down slowly and kind of putter until its warm
