2006 Chevrolet Silverado Hybrid 327 LM7 0.00 +0.00 +0.00 No sheet
Mods: We didn't dyno this vehicle but we included it because it's such a special truck. This is a 2006 Chevrolet Silverado Hybrid. Yes, we said Hybrid, not Flex Fuel (which is what we thought at first). We didn't even know these existed until the owner called us. We did a speedo recalibration for this truck, as the owner swapped out the factory tires for 35" tires and 4.56 gears.

2002 Chevrolet Corvette Z06 347 LS6 355.05 +9.20 +26.29 Dyno Sheet
Mods: Manual Trans - Cold air intake. In the top end, this car behaved a little strangely. While peak HP only rose 9HP, in the mid range, we saw 20+ HP gains. We suspect the exhaust was holding it back, or perhaps there was valve float.

Mods: Automatic Trans - Magnaflow mufflers, Cold Air Intake. This car is literally 3 weeks old and only has a few thousand miles on it. We also adjusted the transmission shift parameters on it to make it drive more like it should.

2002 Chevrolet Camaro SS 347 LS1 0.00 +0.00 +0.00 No sheet
Mods: We liked this car so much we decided to put it on this page, despite not having dyno'd it (we sold mail order tuning to the owner of this car - although he says dyno sheets are coming, soon!). This is a 35th Anniversary Edition Camaro SS Convertible, in the pewter color. Sharp car!

Mods: What? A Ford?!? Yes, we can tune these, also! This was a really well-built 331 stroker, with aluminum heads and a lumpy cam. This car sounded good, and ran strong!

2003 Chevrolet Silverado 262 0.00 +0.00 +0.00 No sheet
Mods: We road-tuned this 2003 Chevrolet Silverado V6. The truck had an aftermarket exhaust system and a cold air intake. We were really able to improve the driving characteristics, despite the fact it is a V6!

2006 Hummer H2 364 LQ4 0.00 +0.00 +0.00 No sheet
Mods: We road-tuned this H2 Hummer. It had a very conservative timing curve from the factory, and we dramatically improved the seat-of-the-pants feel of this monster truck by increasing the spark advance and tuning the transmission. This H2 has full custom exhaust, headers, cold air intake, TB spacer and aftermarket spark plugs!

2008 Chevrolet Corvette (C6) 376 LS3 651.00 +0.00 +0.00 No sheet
Mods: This is one hot car. It has the STS twin turbo kit installed on it, which can run at either 6psi or 10psi of boost, depending on whether the water/methanol is enabled, or not. At 6psi, it made about 520RWHP, and at 10psi, it made over 650HP at the wheels(!). We did the entire tune on this from scratch (with guidance from STS), as STS didn't have a custom tune for the LS3 at the time. In fact, we were told they hadn't previously had their turbos installed on an LS3 at the time, which if true, would mean we tuned the first STS twin turboed LS3! Horsepower/TQ gains aren't shown here because we didn't have a "factory tune" to start with on this one.

2008 Chevrolet Corvette Z06 (C6) 427 LS7 456.00 +18.00 +18.00 No sheet
Mods: Here's another one-of-a-kind - this Z06 has a 6speed automatic transmission in it. Yes, the same 6L80/90E used in the regular Corvette. This customer wanted us to transplant the transmission. Tim at Meridian Performance did the swap and wiring, and we made the computer pieces work together. We have a special writeup on this car in a different section on the site, but all we can say is WOW. This car was amazing, and the automatic transmission did not dull the character of the car as one might expect. With our tuning, we were able to get the car with 5HP of its original dyno pull with the manual transmission!
