Message: [QUOTE="Riverside, post: 911923, member: 12953"] Truck is back up and running again so here is my initial impression and rough data numbers from running high power Jr's 76/59 on stock fuel and Gearhead race tune.* From a dead stop spool up is just as good as my old TPP 72/59. The 76 spools more aggressively.* What I mean by that is weather your just rolling into it or mashing it to the floor it has more pull to it while spooling.* The 76 is just as smooth at building boost as my ol 72 but the 76 just wants to go, witch translates to pulling harder through the middle and top. It just feels like it has more punch to it. Back pressure is down overall.* It will still climb to low 80s (absolute) in the very top part of the RPMs at WOT. Peak boost is down slightly from 60 to 54 EGTs are down as well. WOT have produced 1350 egt were as the 72 was around 1475 - 1500s Cruising temps are also down 50 - 100 Rolling into it fairly hard temps didn't break 1000. Overall, *at least on my truck the 76 feels like it makes more power....spools as good.....dropped EGTs enough worth noting and drives as good if not better then my 72. IMO its a worth while upgrade (especially if more fuel is added) over the 72 that im very pleased with. Again, keep in mind I've had a 59mm vgt with the 72 and 76. [/QUOTE]
