Curtis,

The GM PCM will handle up to 30 LB injectors, I have heard a few 36 LB =
programs but with some problems running rich.

I assume you will be running a blower or NOS to get up over the 800 HP =
mark.

I am running two sets of injectors on a custom intake manifold on my 95. =
I plan to install the complete Electromotive system soon with the Crank =
trigger set up as well.

Hope this helps.

Curt

    I have a 96 Impala SS with an LT1.  I also have a bare LT1 block =
that I plan to bore and stroke to 409.  I already know about all of the =
mechanical pitfalls I will hit, but wondered how much HP will the stock =
PCM handle with reprogramming and about #52 injectors?  Will I be able =
to do it?  If not, what PCM should I use?
