BEFORE BEGINNING INSTALLATION,
READ THESE IMPORTANT NOTES
For all vehicles except 1995 Tahoe, you MUST purchase a separate Edelbrock
Fuel Pump Kit for this installation; single fuel tank vehicles use Edelbrock
#3581, dual-tank vehicles use #3580.
CHECK the Kit Contents and Suggested Tools lists on page 2 to be sure that
you have all items necessary to finish installation.
Make sure this kit is for your vehicle.
This kit is designed work with stock cylinder heads and camshaft or Edelbrock
heads and camshaft developed for this application. Stock compression must
be maintained plus or minus two tenths of a ratio.
You MUST change your computer chip for this kit to function on your vehicle
and be emissions legal. Complete the Chip Information Card and return to
Edelbrock. We will send the computer chip within the continental U.S., free of
charge via UPS second day air. Orders outside of the continental U.S. will be
shipped via the best method at the same costs as continental UPS second day
air. If requested, customers may pay for expedited shipping by providing a
current Visa or Master Card.
Your vehicles wiring harness and electronics must be in good shape or you
may not get maximum performance and/or may experience problems. The TBI
will work with less adequate connections, but the Performer Multi-Point EFI
System is much more sensitive than a stock TBI.
Read ALL instructions before beginning installation.
Note that fuel tank or bed of pick-up MUST be removed.

IMPORTANT INSTRUCTIONS
for ordering your FREE Edelbrock computer chip
You must use an Edelbrock chip with the Performer
Multi-Point EFI conversion
You must change the computer chip in your stock computer (ECU) for proper functioning and maximum
performance with the Edelbrock Performer Multi-Point EFI for 5.7L Chevy/GMC engines.
To receive your computer chip, please complete the attached postage-paid card and send to Edelbrock.
After receiving your card, Edelbrock will send the computer chip within the continental U.S., free of
charge via UPS second day air. Orders outside of the continental U.S. will be shipped via the best
method at the same costs as continental UPS second day air. If requested, customers may pay for
expedited shipping by providing a current Visa or Master Card.
When filling out your information card, please print clearly.

1. The ECM is accessible in pick-ups by removing the glove box liner. This requires removing four (4)
small hex head screws and pulling out the liner. The ECM sits vertically in a plastic cradle on the far
right side of the dash with the connectors facing to the rear.
2. The Broadcast Code is stamped on a white paper label, located on the top of the ECM. Typical codes
for the 5.7L run from AKSM to BDXX, increasing alphabetically with later release dates.

INSTALLATION INSTRUCTIONS
for Performer Multi-Point EFI System
for 5.7L TBI-Equipped Chevrolet/GMC Vehicles
Catalog #3501 for 1993-1995 Model Years
Catalog #3502 for 1987-1992 Model Years
APPLICATION INFORMATION:
Performer Multi-Point EFI Systems are designed for 1987-1992
(#3502) and 1993-1995 (#3501) 5.7L Chevy/GMCs originally equipped with Throttle Body Injection.
These complete systems utilize the stock computer and throttle body unit for a simple and effective
conversion to multi-point fuel injection. Fuel is injected directly into each port in the head for ideal fuel
distribution and efficiency.
TECHNICAL SUMMARY: In 1987, Chevrolet introduced their Throttle Body Injection (TBI) systems.
Produced from 1987 to 1995 on all pick-up trucks and Suburbans, this TBI system was essentially an
intermediate step between a carburetor and true port (multi-point) fuel injection. In these TBI systems,
two injectors are positioned above the throttle blades of a two-barrel throttle body and fuel is injected
into the manifold, much like a carburetted system. This arrangement suffers from distribution problems
because the fuel spray from the injectors does not stay in suspension with the incoming air, resulting
in uneven distribution. Our Performer Multi-Point Systems include an intake manifold designed to
deliver an equal air charge to each cylinder. Each injector delivers exactly the same amount of fuel to
each cylinder for an extremely even air/fuel ratio from cylinder-to-cylinder. This permits us to tune the
system for ideal fuel and spark delivery for more horsepower, torque and improved mileage.
Performer Multi-Point Systems include all parts needed to make the conversion. The stock TBI unit is
retained as an air valve and the factory computer (re-programmed) is also retained to control the
injectors in a batch-fire mode. In the Edelbrock systems, all of the factory sensors are retained and
fully functional. The compact size was achieved by using extruded aluminum fuel rails with new
Magnetti Marelli
®
pico injectors. These are half the size of conventional style injectors.
SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O. #) from the
California Air Resources Board (C.A.R.B.) making it legal for street use on pollution-c
