been sucking at tuning this truck. coming from tuning hondas prior im having trouble with this truck
mods
powermax turbos with high flow adaptors
full race manifolds

Need a log. I suspect you need to increase your LSPI hi. Pretty rich too at .75 lambda
Here is a LOG FILE and updated tune. im still getting only 30 percent throttle at just about full throttle. i cant seem to find the wall im hitting, also in vcm i cant seem to find the right channels ether
New tune 9-11 plus video current.hptupdated log file 9-11.hpl
anyupdates? about to use same turbos, curious what youve found
Increase LSPI HI only. Leave LSPI nominal and low stock. Only add in the 100 and 120 rows 2500 rpm up. Add .1 or .15 at a time until desired boost is reached. You are commanding stock boost levels. Adding to nominal and low will increase boost when lower octane fuels are used. Don't do that. As long as your OAR is -1 boost will remain the same could also be +1 depending on year. If when knock occurs OAR is reduced as well as reducing max boost levels. Also add more to your channels such as all the sources, (fuel, spark, torque, torque max). This is how you figure out what limiter needs to be changed when you hit one. add OAR too.
Edit - wrong thread
Thanks for the help i updated alot of things and the vcm scanner with more information.. seems to be hitting turbo limits also injector limits.
log 3 more driver demand.hpl93 octane correct 10 percent TQ go to.hpt
Anyone has done the tuning for PowerMax turbo here?
