How much additional hp?

Postby 93 W350 LE » Mon May 27, 2013 7:47 pm

Approximately how much power increase is there after turning fuel pin, and bottoming the star?
Thanks,

There's also a little, plastic spacer on your fuel pin that you can remove to get more travel. I pulled mine then just use the coil bind to limit pin travel. That's worked for me so far.

With all the free mods, minus drilling the banjos, and a LPLP, my truck put down 268 horse through a Getrag. I'd bet you'll pull ~75 extra horse with a LP upgrade through an auto.
