HP settings should go no higher then 4. TQ maybe 2. You can boost the rail pressure to 2 or 4 and be good to go.
The thing with 100hp injectors is that the TST box is assuming stock injectors. Before my injectors I could run 9 and not drain the rail. with the 90hp sticks I'm no more then 4 before I deplete the rail
As far as timing, I would work with that. Just listen for rattle, if you hear it, back the max timing down 3 degrees.
Bottom line, Keep an eye on EGT and rail pressure. anything under 20K under WOT, your trying to emulate a 12-valve (over fueling), that's not how a CR works. The TST box will not smoke as much as they used to back in the day, they are tuned rather well, just there's no bottom end. However the 100hp injectors will help with that bottom end alot.
EGT's your are good to hold 1350 all day. short spurts of 1800 is even ok! Just remember to let everything cool down after an 1800EGT run. ;-)
