also, i changed my fuel filter today, and it looks like there was motor oil in the bottom of the bowl. any ideas on what that could be?

Anything else??? What all has been done?..just what you mentioned in the post? Fill out your signature. You need a bigger exhaust, intake, gauges....to start with.

May be just trash from the tank. Clean it out and just keep an eye on it as you change the filters.

im going to do the regulated return when i do injectors


You better get studs and VS's esp with a 38r, the back pressure will be high.

Fuel mods..good idea..
VS's?

i ran with no head studs or valve springs for a couple years with a 38R and 250s with no issues. my boost never got over 35 psi. but definitely love this GQSSB a lot better.
