Hello/Beat that dead horse again! clarification

[BluVette]

OK guys, let me reword the original message and clear up a few points along
the way.

I designed and built and engine. I designed the cam. ACCORDING tot he CAM
GRINDER and HIS computer, that cam is good for 600-650 HP, with all other
factors taken into consideration such as heads and the rest of the
modifications done. *I* limited the engine with 30# injectors, so if there
was any possibility of the stock computer, with a chip in it that has
already been modified for the supercharger.  I'm a mechanic, not an
electronics engineer. Please, whenever possible, put your replies into
laymens terms, and that would help a bunch!  :o) Thanks.
Now, back to my original problem. When the engine hits 5400 rpms, it just
stops. I was told on another list that the computer limits the rpm's at 5400
on a stock L-98 enine in 1989. BEFORE the modifications, with only the
supercharger, it did the same thing. I really need to spin this engine up to
at least 6000....so, does the computer limit the rpm's at 5400 or is
something else doing it?  It did it with the old stock injectors, and i
would have thought that the engine would lean out at a higher rpm with the
new 30# injectors.
Next problem is the idle. It is hunting between 500-700 rpms. The cam is on
the radical side, along with custom made full roller 1.6:1 rockers. I HAVE
to raise the idle up to about 800-850 rpms, as it dies right now when coming
to a stop about 1/2 the time, especially when the engine has been running at
WOT, and then letting off the gas, it dies almost immedatly.
I am sure that there are other factors to take into consideration that I may
not be aware of as of yet. The engine is also equiped with water/alcohol
injection, just ahead of the throttle body to help eliminate detonation, and
that combined with the lowered compression ratio has done a GREAT job, and
no knock or detonation is apparent, even under full boost conditions, so I
don't *think* that the advance curves need to be played with any more than
they may have already been altered by the custom chip that is already in
place.

Someone on the list suggested swapping out the computer with one from a
turbo GM car. Good idea, but, just HOW would I go about this, and is it
compatable with an 89 Corvette onboard systems already in place?

Inquiring minds want to know :o)

Thanks to everyon that has been involved in this thread to this point,
pleasae be patient and I will get up to speed.   TIA!
