[QUOTE="Charles, post: 1409524, member: 103"] There's not.... you just kept mentioning that rpm range so I wanted to know what pw value you were seeing. RPM is indirectly related in that MFD and ICP can be limited based on rpm, which will pull pw down with it. What nozzle are you tuning? Flat to the floor 1.5 actually seems low. Is it smoking? If not you might need more duration in fact. What's ICP? If it's not 3000 when you're struggling for power, make it so. For starters I would err on the way to much ICP too soon until it's bucky and jumpy. Then you can tune in the duration until you max the power available without smothering the fire. Lastly, back the ramp rate for the ICP back down until it just feeds the fire without too much aggression. I can't tell you how many times I have steepened up the ICP table running toward full MFD with great results. Also bare in mind that shallowing up the MFD desired table with increased pedal will control the application of power as the ICP table steepens. Key point again.... if you're struggling to spool and you're [i]not[/i] at 3000psi, steepen the ICP table until you [i]do[/i] reach 3000psi at that MFD value. [/QUOTE]
