No Repository Upload Here are some excellent tunes.
I guess the "new site" still needs some refinement,
there is apparently no "Up-Load" Button,
so, Ill post them here.
I lost my original Tune File due to a failed Laptop,
so the repository luckily had a file I could use as "close enough" to the original,
and I would like to help out by posting my Tunes.
The first one is with a slightly modified Engine and the STOCK TRANSMISSION.
The Mods to the Engine are, Completely Insulated Air Induction Tract, with a 3"Air Inlet behind the Headlight, and,
Throttle Plate Mod, (look it up online), K&N Air Filter, Multi-Spark CDI Ignition Box, Modified Distributor Rotor,
Drilled-Out Distributor Vents, (to prevent Condensation, a problem with Vortec Distributors),
Fuel Injection Spider Up-Grade, (highly recommended),
Stock Exhaust Manifolds with aftermarket 2" Head-Pipes, into a 2.5" Collector, then into
a 3" Very Low Restriction, Quiet, Single Exhaust System, using a Gigantic Magna-Flow Muffler made for Full-Sized GM Trucks.
Remember that this First Tune is for a completely STOCK 4L60 Transmission.
The Old-Skool Mechanical Valve Body in a 4L60E WILL NOT RESPOND TO TUNING the ECU,
unless you modify it with a Shift-Kit, (at the very minimum).
SO DO NOT USE THE Hi-Perf TRANSMISSION TUNE UNLESS YOU HAVE A TRANSMISSION THAT WILL SLAM ALL GEARS.
This Tune "probably" won't hurt your Transmission, BUT I CAN'T GUARANTEE THAT.
Use either of these Tunes AT YOUR OWN RISK,
I know what I'M DOING, but your setup, and experience, might be different.
I will also post a Tune that has a Fully Built, 650 Horsepower Rated, Transmission, with a 3000 RPM Torque Converter.
This is my current Daily Driver Tune, and has very nice Street Manners, even with a potentially brutal Transmission, and
is Tuned to eliminate Wheel-Spin with Huge Summer Radials, and a 3.43 Rear Gear.
The Truck consistently runs a 2.2 second 60 Foot Time at my Local 1/8 Mile Drag Strip, WITH A STOCK, 226,000 MILE ENGINE !!!
