Has anyone had any luck with this on a 2008 Chevy Silverado 5.3? Trying to find something for better gas mileage and more horse power.

Yeah I just bought this for my brother for Christmas. He has a 2007 5.3 sierra 1500. This is a awesome product. You should expect about 30 hp and 2 mpg more than stock. Main difference is in the transmission shift points it keep pulling through the gears. Unlike stock where the shifts are really smooth and you feel like your losing power. Also there are a ton of extra gauges and features to help track your trucks performance.

I have had really good performance and fuel mileage gain from the bully dog gt. I have a 4.8 and I get 22 mpg with intake bullydog and exhaust. I've raced a few 5.3 with exhaust and intake and I always hang a fender or a half a truck on them.

I'm not quite sure if it will fit your application . I have a 5.3 Z 71 Silverado. Pump has been working fine since I installed it.

It was the correct sensor for my 05 Cadilac Escalaede. Don't know about the Silverado but my guess would be they are the same. There is no need to replace both sensors as these sensors rarely fail. Did the OBD reader indicate the left sensor being bad? If so, you may have received a faulty sensor.

I would check MSD'S tech sheet. I think they may have a harness for that. I used their harness to my Ford EEc distribute. It's worth the performance and fuel millage gain.

None, after running it for a while, what fealt like a gain was not, dyno showed same results a a drop in performance filter. Also mileage dropped, to 25 mpg from 29 mpg. I recently returned car back to stock, power is the same, fuel economy back up. Only positive thing about this unit is price, and sound. I had the Mopar unit, prior to this, and a K&N; as well, money wise, lesson learned just buy a K&N; replacement filter and save some time and money. On a side note if you are looking for bling and nice tone from engine, then the unit is worth it.

I suggest calling the manufacturer. They have excellent customer service. I have a 2005 Silverado and it works perfectly.

Hey there buddy it should be fine I have a k&n; intake and straight exhaust with a rebuilt heavy duty trans for towing. But otherwise a stock truck the tuner was designed for stock 5.9l Cummins stock 48RE and stock NV 5600 six speed manual. It adds great power! But not enough to destroy your transmission. Sorry for the long answer but it's better than a "yes" ahaha just buy it adds POWER and economy. Nothing to complain about or regret and that's from having it on for 12,000 miles on the highest hp setting. Great tuner!

Probably, I have a 2005 chevy silverado with 5.3 and it worked for me. Try taking to old one off and remove the Large top and wash it out. I took my old one apart and that was the problem with it.

I was told it worked for my 2005 Silverado and the blower does work but it makes my AC blow out one side and Heater out of other half. I have not persued this delima any further since it is almost winter and was mostly concerned about blowing AC.

It is no longer called the GT Hemi Plus, now it goes by the GT Platinum gas. They use the same model for all vehicles now that are gas operated. Go to Bully Dog's site and check your vehicle set up to see. It works wonders. You can change shift points and all. If you are looking for performance e, I would suggest adding a throttle body from thefastman.com, a cat back exhaust system, and a cold air intake. I have added more than 100 HP to my truck.

Gas mileage seemed to get better when on the highway. Took a trip a couple weeks after installation and got around 18.5 generally. The increase in torque was noticeable. Fuel mileage around town has stayed at 13 this winter however(cold climate).

I have had this programmer on my '96 7.3 for four years. Never a problem, and it does improve the performance . I haven't noticed any better fuel mileage, but it does improve shift points when towing. I wouldn't recommend using it on the higher settings without a full set of gauges -- EGT, Boost, and Transmission temp at a minimum. I put in an extra transmission cooler just to be safe. Running at higher power settings puts extra stress on the engine and tranny and makes things run hotter. Running synthetics will also help keep the heat down.

I currently use this for my 2005 chevy silverado and works better than the OEM tool that went "missing". I doubt the component this interfaces has changed between our two trucks. Might be worth checking out since it is sold and ships by Amazon...would make a potential return easier.
