Port & Polish GM 5.3 Throttle Body 

That is false! It depends on a few things actually. If you have a vehicle that is not able to drive legally down the road then yes it will need to be reprogrammed via scanner. If you can drive it then there are a couple of methods you can use, but rarely does it just relearn itself.

You should be fine. I recommend to anyone that if you think you might be getting close in an area that might cut through, that you reinforce those areas with JB Weld in advance to cutting and polishing. Easier to cut into cured JB Weld than it is to cut a hole, patch it and then try to continue where you left off...

SDyacht where is this fuse located? Under the hood or inside the truck?

Nick Huff anything bolt directly to the 2003 GM 6.0L?

Any particular year of the G8?

Also, if I remember the TB in the video I made was from a 2006 or 2007 Silverado

Hi Edgar, Sorry I'm just now responding to you. I started a new job in an office as an engineer and I'm no longer working as a mechanic out of a shop. If you were here in San Diego, I could work out a day with you, but if shipping is involved, I have too much going on right now to add more commitments. There is a guy I've spoke with and emailed a few times who is on the east coast who also does this. He mostly does just the TB's for the Colorado's and canyons, but he might do one for you. You can search and find him on 355nation.net. Or you can do it yourself if you have a dremel tool. It'll take you longer, but when you're learning, going slower is safer.

Yes. Since I stopped running my own business and went back to finish my engineering degree, I only do this on the side by request.

SDyacht do you do the mas air flow sensor?

You would have to send me yours. I tried keeping some stocked, but the demand is not high enough to make it wort my time. And I was stealing business from a guy on the east coast who made it his mission to trash talk me for only charging 1/3 of what he was charging... In "his" defense, he did made the effort to spend money to take his truck to a Dyno to prove his numbers. My proof is in the seat of your pants! Just as verifiable as all other results, but I didn't waste my time talking sh!t in web forums. Just like the dilbert who was saying I have no verifiable results by claiming he has dozens of satisfied customers, so do I. If I had a personal Dyno, I could perfect my P&P, but than I'd have to charge more.. This conclude my longest response that I've ever given to criticism. *not worth my time to talk crap*

if i had extras and my truck i want this done on wasnt my daily id definitely do it if the price was right, i work at a chevy dealership and the fuel guys have a few of these throttle bodies somewhere but im not sure if they work or not so ill go see sometime

I've been busy and didn't see your comment (6 mo ago...). I can, but you need to email me directly at SDyacht@gmail to discuss what you want to meet expectations.

Then you've heard wrong. However it does affect different vehicles differently depending on the size of the motor, the factory design of the throttle body. There are plenty of variables that all play a factor. In this particular video, I am doing a GM 5.3 TB, and it makes a HUGE difference with this motor :)

Joe Kearns my Sierra has the 5.3l Still, many on GM forums have said this doesn't really give you much. What does it give? Quicker response?

No, porting and polishing, be it on a TB or a head or an intake are all about adding more air into the system. The more air you get the leaner your A/F mixture which results in your FI system adding more fuel to get it back to the correct A/F ratio. This all results in more power. This is the general theory behind porting and polishing. But like Joe said, it varies with every setup.

the gains for this is more felt when the tune is also modified. on a GM truck you actually get more seat of the pants feel from changing the shift points in the transmission then you do from changing the engine tune when it is pretty much stock. GM stock tune on automatic trucks is where they limit the power and torque to keep warranty on drive train issues down. by changing the shift points you also extend the life of your transmission.

Re watch the video and use your brain to play the tape forward...

+SDyacht dude I said that like last year, I work at a Chevrolet dealership now, I know how to take them off now lol
