You are smart not to run any kind of tuner or chip w/o gauges. Those trucks came pretty fast from the factory so I'd be real careful adding power. I'm not against modding diesels if it's done intelligently but often it's not.
Good luck with it!  |
Agreed. A K&N filter (previous owner) lead to the early demise of my 914/6 engine. After the rebuild I switched to paper filters.
