[QUOTE="TARM, post: 76025, member: 578"] Yes you were being careful. I kn ow if I was doing my own tuning pucker factor would have been off the chart. LOL You have a better hold of all this as you are playing with it all. But my guess would be do whatever to PW ICP to bring a 800-850 tq. But start lower and bring it up with RPMS. Set that PW as your max or how ever that works. Then I know there is a table that correct SOI for RPMS to keep it from retarding as RPMS increase. So that holds it. Then slowly advance the SOI say around where the TQ peaks and starts to drop. But of course keeping it in the sweet range the whole time whatever that works out to in crank shaft degrees to keep the stress on the rods, their bearings and wrist pins in proper alignment. Not sure what tune changes etc there is after the TQ starts to fall to extend that HP. I know I am likely boggering this up but hopefully thru it you get the idea of what I am trying to say LOL. Basically ramp both HP and TQ up rather than any flat lines and keep Tq which is CP below a set limit and SOI in the sweet crank degree angles. See how far that will extend out the TQ peaking @ 850 and where that can take HP carried out to. I am starting to look into those CP monitoring logging systems. As that is a tool that could be golden for tuning and now costs have gotten out of the 10s K and down to 1/2 that. [/QUOTE]
