I installed an Edge Programer on my truck, Was to jerky when shifting for me. Runs like hell though! Don't know if the extreme mode was responsible for the shift problems or the speed sensor on my grar vendor box. I just left the programer on "normal" mode now.
OK...truck is all fueled up, all fluids changed. Two speed gearbox to help going up grades and better mileage on the flats. 1,400 miles at 15mpg. $4.50 a gal in s. ca. Looks like $4.00 a gal. from San Francisco on up. If I can keep my foot out of it the gas shouldn't be to bad (gasp!!) When we get home it will be time to install a 6 gauge instrument cluster. silver dash accents and...maybe a train horn!
I have a 2009 serria 4.8 ltr. Does any one out there know if this engine has roller rockers? What ratio they are??? Thanks!
Well got my truck back from Gear Vendors today. They replaced a switch (oddly enough a GM part) that was faulty! Shifting great now. They were taking pictures today for their updated web page, used my truck a vette,a great looking (and sounding) Javelin and a nice old chevy coupe. Good to get rid of the rental truck they got me!
Well went to dealer with "Edge Programer" dis-connected and they were able to get codes. Tranny os OK. Tomorrow back out to Santee for "Gear Vendor" to adjust the speedo sensor. (or so they say)
