Valve Train noise

[George M. Dailey]

You may not like what I'm about to say. In my opinion you should junk the
Electromotive ECM. Buy an GM MAF type ECM ($100.00) and prom ($50.00) build
or buy an engine harness. You will then have a system that is well proven
(over 1,000,000 units)and supported. Unless you are using after market ram
tubes, plenum, and base, your best performance will come with the stock
components. All of the stock TPI components are designed to work together.
When you buy into the "bigger ram tubes - more flow" thinking, remember that
if 50 extra horses could be added by only using a larger what ever, GM would
have done it. The cost to cast a bigger throttle bodie, ram tubes, or what
ever is probably pennies. GM spent millions developing TPI and it works. The
MAF will, of course, help you if you have a warm cam. 

Don't feel bad. After market parts can confuse even the most seasoned hot
rodder. Some of the venders are liscened and bonded LIERS. Oh, it's not a
total loss though, I've heard that the Electromotive ECMs make excellent and
attractive door stops or paper weights:}

Good luck
