1997 E7 427 power upgrade
in Mack Truck Q & A
Posted
I have a 97 E7 427 and I pull 80 to 95k regular. I'll like to have a little more pull on some hills I have looked into turning the fuel up but have not gotten any response to where to do so. Also looked into getting larger injectors and turbo but ran into a snag there. I've seen where most have a s400 turbo where mine has a Borg Warner 053A is that the same as a s400? Where or how can I get cheaper power?
