2006 Blue over Primer'd Bondo FPR 6spd #23424 slapped together 2/22/06
I don't know if he has learned since last year, but as of mid-2012 Jeremy Formato did NOT know how to adjust my '06 6-spd for 4.56 gears.
I had genuine NOS American Axle 4.56 gears installed by Lonnie last year; it took several attempts to get them not to whine (even though they still do a bit under load and when decelerating). After we were done I drove over to Jeremy Formato's at FasterProms to have the truck tuned per Lonnie's recommendation. Jeremy tuned the truck actually towing a Uhaul trailer (loaded with a piano that I was delivering to my Mom in Miami) as my main use for the truck is to tow my Airstream; I want low end torque more than high end horsepower. Jeremy also installed a ported and polished throttle body. Jeremy was kind enough to tune the truck late at night; he was pretty tired, and he worked pretty fast. But, the main reason I went to Jeremy was to have my speedometer corrected since I have a 6spd with 4.56 gears, and I made this clear to him. Over the phone, prior to having the truck tuned, he stated what I wanted to do wasn't a problem. But, halfway through the tune he informed me "I might not be able to get your speedo right...I remember there's an issue with these trucks, on the later models" which honestly took the wind out of my sails. The only REAL reason I was having the truck tuned was primarily to correct the speedometer from the newly installed 4.56 gears; the performance gain was simply a by-product of the essential nature of getting the speedo fixed. If he had told me he didn't know how to do this I wouldn't have had the truck tuned by him. He is apparently very well respected and well-known for LS tuning, and I figured for sure he knew how to adjust for the speedo-especially since he said it wouldn't be a problem-but I am out a good chunk of change for the tune (he DID take off $50 for the speedo problem...but the tune was worthless without the speedo working). He was a nice guy, and went out of his way to tune my truck, and I was totally happy with his tune performance-wise, but cruising at 65 while the speedo says almost 90 just wasn't gonna cut it. If it was predictable (say, always 10mph fast) that would be one thing, but the amount of error varied with speed. Totally frustrating. I wasn't a happy camper that night as at that point my speedo was horribly off, it was 12am, and I was out a few hundred bucks for a tune that I was going to have to have re-done right away by someone else for several hundred more dollars.
I ended up shipping it off to Bryan at PCMforLess...who set the speedo exactly right.
Lesson learned. HARD. As in almost $800 hard. Phruck.
