supraman Posted January 12, 2008 Report Share Posted January 12, 2008 Since I dynoed, the trucks info center is telling me I need to service the brake booster...is this a coincidence or does this happen when the front shaft is pulled? BTW 455 whp and 497 wtq on 15* timing and 9lbs boost. It will dyno a lot higher now that I have new plug wires...one was sliced and one had a broken/rusted connector to the plug itself causing a terrible missed and sputter that stopped the pulling at 5500...by 5600 power was down to 300 whp which leads me to think that it would have kept pulling up to my 6100 rpm redline as it was pulling really hard up top that point.
