I bought my truck used with 28K miles It had pulled a fiver alot. I have asked a question before about the waste gate and this line you can remove or block It goes from the afc thats the part with the star wheel right to the waste gate thats on the under side if you will of the turbo right? anyway I have not got that line on my truck?? I have from the rear of the afc to the intake a small line looks stock nothing else off the afc like that then on the turbo on the front side down on the area that connects if you will to the intercooler hose. there is a elbow looks brass which has a 3/8 rubber line connected to it which also connects on the waste gate only line on the waste gate is this line. the turbo end has a reg radiator clamp on it not stock the waste gate end has a regular stock looking clamp. Having said this I am trying to understand if I have some mods already The afc has a break away screw but it also looks like it has been removed?? I suspect by a glue spot on the inside dash where gauges may have been?? any thoughts would be wonderfull Thanks so much Patrick
