Before My car would lag then take off like a rocket and other times it would just take off with no lag. That makes racing unpredictable and sometimes lesser cars will hold up untill the SC finally kicks in. I would recommend changing to the Johnsons for anyone with a SRT6 whether your going to further mod it or not. Bite the bullet and spend the change.
Ok so this is going to sound like a really odd question then so bare with me...
Is there any change to the SOUND the car makes when the performance was different from one time another? I noticed that (while it may be all in my head), the times when I feel I am getting the best performance from the car, the exhaust note is strong and unmuffled, whereas when I feel a lag the exhaust hum sounds more "airy" and not as strong.
I have no idea if I am making any sense.
