Hi there, the name is Brett. I am from Hollidaysburg, Pennsylvania. I have a 2005 Mazda 6 3.0 It's been a project car of mine for a few years now. So I just fully rebuilt the 3.0.

I had the block shaved down, both heads shaved down and the cylinders resurfaced. I ordered a stock rebuild kit from Chegg. I have an after market intake, after market headers & full out exhaust system.

Premium coil packs and OEM spark plugs. I would love to know what else I could do to achieve some power with this vehicle. Where is a good place to get the car tuned at? what is a good programmer for the computer? I run Amsoil in my vehicle. Ideas for my handling and suspension as that will be the next areas that I will be working on.

Now as for why I am here. My build is back together and running but is running through gas like crazy.

I am going to check the gas regulation module tomorrow to see if that could be the issue. also I keep getting random cylinder misfire codes coming up and the car has a slight misfire. Its really noticeable between 2500-3000 rpm.

Also none of my o2 sensor are reading much of anything and they are all brand new, would this be an issue because of eliminating the cads? Do I have to bypass these codes somehow? I have a lot of money into this car at this point and could use some help.
