DETAILS:
Software: EFILIVE
Subject: My truck
Total cost: 200$ (100$ license, 100$ Erik's time)
WHAT WAS CHANGED
Shift firmness: 2.5 (on a PCM4LESS scale)
RPMs at idle: Stock - around 612, Tuned - 680
Shifting RPMs: From 2nd gear to 3rd he changed to 5900 from 6100 and TC lockup happens more quickly.
A/C shutoff: Stock - 8000RPMs, Tuned 3500RPMs
K&N and Exhaust: TUNED
Governor: Couldn't take off (didn't mess with too much)
Octane: 92
Max speed in reverse: 55MPH
Speedo: He didn't touch this but yet it fixed itself so now its about 1-2 MPH off.
And the truck doesn't stall when you want it to go forward, when you press the gas it actually speeds up almost instantaneously.
STORY
So we started out by purchasing a new license for my truck which is VIN specific which can only be used on my truck. He first pulled ALL of the data from my truck I.E. spark, shift points, RPMs, etc, etc.
He then continued to modify just about all perameters of the stock tune on my TB that came from the factory. We then flashed the PCM and connected his laptop so we could do a real driving dyno tune run to make sure he tuned it so it shifted correct etc, at this point he was logging all real time data on his laptop so we could see what the spark is and see exactly what he needed to fix. He had to smooth out the graph quite a bit to get the TB at its prime.
We found out that my TB needed a new t-stat and to be cleaned because the spark was way too high in the 2500-4800 RPM range at WOT.
After I fixed everything we tuned it some more and putting in a new t-stat got rid of just about ALL of the spark IN ALL RPM ranges.
There's probably more I missed but will add later.
Overall I'm EXTREMELY pleased with the results of this tune its a different beast of a vehicle to drive which makes it more fun to drive. With all that was done I probably saw an increase in about 20HP at the rear wheels now the power to the wheels should be about 210-215HP at the RW *THAT IS JUST AN ESTIMATE*
Ill try to get a copy of the tune from him so I can share more of what was done but no secrets can obviously be shared as it is his work and I know he doesn't want it being stolen by anybody.
