Program

[Francis Aldridge]

Just installed a Magnuson supercharger. Imagain the look on my face on first run and fell flat on my face at 99mph. Magnuson won’t release the program to openlimiter so I can get down the track. Have never raised or lowered the truck nor would I and tires are speed rated “V”. Any help. Retired Marine with a dream. SEMPER Fi thanks

You need to replace the driveshaft first. They can't handle much past 100mph. As far as raising the speed limiter I'm sure someone can chime in on that,

1slow1500 probably knows how. He's pretty smart about these trucks. Pm him

The limiter is saving your life..... 3/4 ton trucks are NOT built to go 120.

 

Driveshaft will shred... thne bad stuff happens....

 

If you want to go 100 plus get a Camaro, seriously do yourself a favor.
