[QUOTE="Six_Sloww, post: 1409922, member: 13248"] Been battling issues with hot fuel, way hotter than what people with similar modifications are seeing also noticed my injectors are really loud lately... Took me a while to notice but my Rail pressure is way too high. Going 40mph down the street just maintaining speed I'm around 25k. Highway at 80 I'm damn near maxed out around 30k (max for me is 31.5) What happens is while I'm accelerating everything is normal, somewhere in the 15k range. When I get up to speed after about 15-30 seconds of maintained pedal position my Rail pressure will jump up 5-7k. If I let out it drops back down for 15-30 seconds then jumps back up The tuning didn't change, but I did try to swap over to an h&s canned tune to see if it went away and it didn't. Any ideas?
