Downsides to Changing Timing
#12
While the case is open pull off the pump gear rotate the pump and put the gear back on so its one skipped tooth. If your not running large aftermarket injectors, head studs its too much timing. also too much if you use the truck to tow.
Most people can get by by just advancing the timing with the amount of adjustment the pump has stock.

I think id skip a took then put it to the stock mark... Im at 1/4" pas the mark now but my injector lines are stopping me from going farther and stuff is really tight by the pump... I figured it would be close to where i am plus i could get to my pump when i need to.
im running 8x11's by the way.

a tooth and the stock mark is not near 1/4" bump. Loosen the injector lines at the pump and use a ratchet strap to pull it over to the head some more, if it still has a problem moving use a rubber mallet to help it along.
You could skip the tooth and then retard the marks some to get closer to were you are now. I really think that if you move your pump some more to the head you will have all you need.

All I know is just what I did made a night and day difference with mine and it's an AUTOMATIC.
Kinda' cool to look back, mash it, watch the smoke dissipate as the turbo spools up, while FEELING it when the turbo lights off.
A good automatic, which mine is pretty decent, will let you feel the power come on.
You can't get that feeling as noticeably with a manual, because shifting manually upsets the curve, but I am without a doubt a manual transmission lover.
I can only imagine how it would feel with some REAL power coming on.

This thread is informative. I like it.
I think my truck could benefit from more timing. Back in the day when I was running DDP4's (old version) and an HE351 with a 3/8" timing bump, the truck was pretty awesome up to about 115 (estimated)
With what I am running now it craps out around 90. 55-90 is pretty good though. I also see some black smoke when I mash it in OD. I don't think theres enough timing with how it is now (pump at base timing mark + dynamic timing spacer) to burn all the fuel. I could be wrong though. Unfortunately my IP was reinstalled with silicone (I didn't do it) so it is stuck at base timing.
Maybe one shouldn't be driving a first gen past 80 mph anyways, I don't know. It sure was nice to shut down a 6.4 Ford (it was probably stock) that thought it could pass me though.

I can't even imagine going 115 in my truck. I know that between my ultra bouncy bench seat and the stock 4x4 suspension, even a small bump in the road feels like a speed bump. Heaven forbid finding some railroad tracks at about 55mph......
In any case, I guess I'll leave the timing alone.....well at +3degrees that is. In all honesty, the only trailer that I might ever have to pull is a 16' flatbed, so I'm not too worried.
