just got done turboing my stock a6. before the turbo install it was around 145 in all the cylinders. now after driving it and street tuning it its still right there. all cylinders are within 3lbs of each other. my question is, will adjusting the valves maybe give me alittle more compression? i know the motor is kinda week b/c i got walked hard by a z6 with alot smaller turbo also stock motor. so is it worth maybe adjusting the valves?
