Re: RC4WD 4200XL models and nomenclature?
Ok, so heard back from Tang and he said the newest 1.5's do have an improved 3 valve block and not a 4 valve. He also said to make sure the flow isn't too high and stay at stock or a bit lower on the pump speed which we all know already. Seems a bit suspect until I see a listing to buy a "new" 3 valve block upgrade. If anyone has some pics of their 1.0 3 valve block could you post up please, would like to compare.
