Before I link the video and post my questions I just wanna give a tiny amount of backstory as to why I turned Ernest up 2 flats. The truck always does pretty good for being n/a, I think the banks power pack air cleaner and the larger exhaust/ better Y pipe whether it came from banks or was a back yard job helps the truck a lot with egts but the truck was just starting to struggle with larger hills if it wasn't getting revved up to 2700 rpm or higher to keep the rpms up for the next shift.
Even with all that, I could not get egts past 1000 and it didn't smoke 1 bit at wot over 3k rpms towing uphill. [Not that I care at all about smoke] Not that you want to be over 1000 ekgs but the truck just didn't have enough fuel to help itself and there was some room there so I figured I'd go for it. I put a "new" pump on from a 93 na tow truck last year that had 67k original miles so the pump is old but not dead. Stole its injectors too and kept my old stuff as spares. I have a mini moose or baby I can't remember which on my 6.9 which really woke it up but if you hammer down on it you can get the egts into unsafe levels [it doesn't have the intake and exhaust this truck has though]
So here we are..
Now it's really alive. Doesn't feel like the same truck, and the truck is not a fan of that hill I'm on and I didn't even give it a running start at the bottom and didn't hammer down to wot until I put it in 4th.
I would have left it in 5th for the video but I've never been able to get to 5th on that hill unless I get a running start at the bottom so I was unprepared.
I took another run in 5th after the video and if I leave it at wot I can get the egts to unsafe land but it takes over 20 seconds straight and I can back off to 3/4 throttle and hold it right at 1100 and I trust the pyro it's a good isspro one between the two pistons that fire one after the other.
I guess my main question is if you were me and turboing this truck wasn't in the immediate plans [I'd likely turbo my other idi first] would you leave it up 2 flats and monitor the egts when your ramping on it or go back to only up 1 flat? I'm not really harming anything as long as I pay attention and if I'm not purposely mashing on it it doesn't smoke near that bad.
