I've been driving my '97 12 Valve lately since we've got everything hooked up and running well. Since it is a completely rebuilt motor, I've been taking it easy with my right foot and putting around keeping it under 2500 RPMs or so. But today and once a few days ago, I stepped into it a little getting onto the interstate and took it to 3000 RPMs moderately getting into it. The turbo spooled quick (Borg S369SXE FMW) and i was happy with that, but what I noticed when I reached about 2700 RPMs, the boost gauge read 40 lbs. and never went higher or lower until I shifted. Also, it felt like the power was topped out right before I shifted. The pump was rebuilt by Antrim Diesel and was supposed to have the original 4K Governor Springs that I had previously installed. Is it possible my pump doesn't have the 4Ks in it? Or could it be something else in my system? Fuel Pressure stays at 40 lbs. the whole time, timing is low at 13* but after the break in will be bumped to about 20-22*, and I have no boost leaks or anything like that. Any of the experts have any ideas/suggestions?
