The old 12 Valve is getting a little tune up...

I just dropped my truck off this afternoon to get a much needed tune up. It's a 98 CTD 12 valve Quad cab 5 speed with 105K miles. I needed to have the KDP done as well as a new serp. belt and a new fuel solenoid boot installed. I recently replaced the fuel filter, rubber fuel lines, lift pump and a bunch of other crap.

Now I'm having a 4K spring kit installed, the fuel plate will get a little grinding, I'm having a 4" Magnaflow exhaust installed with no cat and a straight through muffler, having the timing set as well as adjusting the valves and the injector pump timing. He'll also turn up the injector pump and see how much power I can get out of it before I start eating up the stock clutch. I'm looking for a balance between decent power and reasonable EGT numbers, I know I can take it higher but I don't want to be past 1050 - 1100 when towing if at all possible.

Can't wait to get it back and feel the difference, she's been feeling very sluggish lately. :)

dont forget the fuel overflow valve. thats usually the culprit before the lift ppump on one of those goes out. the old 12v lift pumps lived long lives 200k was average and even then you could keep it as a spare most the time
