Nope. It really isn't building boost. Even on a long hill in 3rd
it reads Maybe 1.1 if you are lucky. I used to see 1.3 and even 1.4
"once" in my friends Stock 5ktq. And it felt WAY faster than this. This
car is slow. And according to Scott Mockery the gauge is semi-accurate
except it can only read to 1.3 or 1.4 and not say 1.34 but that it is slow
to react so it is usually 0.1 behind the ball but a long uphill may let it
catch up. Anyhow, I know there is little boost to no boost.

His mechanic "said" he replaced it a few months ago but I'll look
at it again. I'll check scotts page to see how to tell if its new.

Nope, late 87' with Bi-Level. This BI-Lev appears to work. But,
do you still think it is the head? Do you HAVE to have one with the
Bi-Lev or are they interchangeable. Can you upgrade an 86' to the Bi-Lev

Thanks. I just know what I have read on the list and heard from
my friend that has one. Luckily he has had no real problems though.
