I've searched a little bit but i don't think i've found the right answer...

I have single turbo with ported engine and my car has been tuned about a year ago by Steve. I don't drive the car much... maybe about once or twice a month... I change oil and all the fluids regularly as i clean the spark plugs and stuff like that...

Lately it's been running a little rich... What makes the car start running rich when it wasn't tuned that way and everything was normal when it was tuned?

I haven't changed anything on the car since the tuning. The wires i custome made because i relocated my coils... the spark plugs are all 9's... Fuel injectors were cleaned by RC before tuning... etc...

Well, let me know what you guys think....

Thanks

 

do you still have the airpump? if so check to make sure its working.
