Sorry my post didnt all go on, my problem is when u running the truck hard in like 5th gear in a 6 speed at high rpm's. Like it starts cutting out around 3k rpm's and struggle to get to 3700. It will get there but it cuts out bad, u should be able to tell by the datalog and the fuel pressure sensor is hooked to drive pressure. Im running SO pump and had a Dragon Fire Extreme that did the same thing. Mach 4 injectors that has SAC nozzles 425 studs and fire ringed fass 150 that dont drop below 12 psi HE351VE with fleece controler I can run the TST COMP with Quad set on 3 and the tst turned up and it runs great all the way to 3700. I also got a 4k quad that runs good, ive ran different tunes and they all run fine on 4k. I need to hook the redline up and try it, The hardfuel box has always did this as far as i can remember i sent it to quad and had it tested and he ran it on his trucks and said it hesitateded at 3000 rpm's but he said it went to 3700, i think its something in the box that when it has a hard load on it, it trying to kick out. Its like u are turning the key off and on. The box runs fine long as u have it not doing wire tap. So i think its in the wire tap fueling on the quad that im having problems with. I would like to let someone that has close to the same set up try it on there truck, i really like to get the box straightened out because im changing my set up with a bigger charger and going back to a bigger pump and bigger injectors, I like to have box working properly for the street So i can detune it. I hook to a sled 4-5 times so i run a aggressive tune. Thanks

Here is the tune I am running...
