Just thought I posted myself and few others have notice the car doing this.... when just playing with the fuel controller if u add fuel to the car on the upper range it causes the car to white smoke.... just like it does when u have a valve seal going out... it does it at idle or anotherword sitting at the red light.... anyone have a clue it does that.... I mean if u turn the setting back to stock or take fuel out it doesnt do it.... only does it when u add fuel... as if the valve seal were leaking but go away when u turn fuel back down to stock or less then stock..... weird just wondering if anyone else notice that or knows why it does that... thanks!!!
