hey guys,

I'll be getting my TA in couple weeks and wanted to get some background on what is the best way to determine what timing to run. should i just start at 10* and go up by one till i hear it ping then back it off one? just curious to see what to do. also, the TA is a must as the only way to adjust correct? i know the preditor has the ability to change the timing settings, but can it actually do anything on its own without the TA?

Yes.

Yes. The TA you're getting does it mechanically. The Predator does it electronically, via the Engine Computer. In fact, the Predator only alters timing at WOT, and it adds timing proportionally. It adds a percentage of base timing. So if you set the Predator to +10% and the normal timing at a specific RPM and load is 5*, you'll get 5.5* -- a difference of 0.5 degrees. If the normal timing at another RPM/load is 33*, you'll get 36.5* -- a difference of 3.5 degrees. With a mechanical timing adjuster, you'll get a fixed amount added to all points in the timing table, WOT and part throttle.
 
wow, very informative.... i suppose the question would be then, do they work well in tandem, or will it not make a difference considering the mechanical TA. or... would you be best doing something of the following:

max out your TA at say 15*, back it off to 13 for every day driving, then use the preditor to max it say 15% for WOT....

interesting concept to be sure. thanks for the info

You don't want to run them together. The TA is actually more of a way of fooling the EEC, by changing the position of the crank sensor. Both work well, you just need to stick to one way or the other.
 
I'm, getting a killer deal for the TA/UD pully combo so i dont think i can pass that up. when i do get the preditor i'll pull off the TA and sell it then and just run the pred, but i dont forsee the pred till another 6 months at the earliest.

I ran the T/A and underdrive pulley combo until my KB. Your timing depends on what gas you have(octane). If you can get 93 or 94, you can set it to 16 or so, if you can only get 91, set it to 14. I know by experience. I was stationed up north and had 94, I am now in So Cal so I can only get 91.
