Ported the throttle body on my 05' CTS-V about 2 weeks ago, turned out real nice. Since then, I can tell throttle response is greatly improved, and I say the car just feel more responsive?? Now. Not sure about any power increases. Although, now my gas mileage has gone to ****! Ide say a good 5mpg's down. And not the exhaust pops inbetween shifts, which it didn't before.

Just wondering if this is a tune issue? Didn't know something so small could cause all this. Lol

seems as if your tune was affected.

Deffinatley not the case here! I guess I'll have to get the tune looked at. It had to of messed with the MAF I guess, like I said it's popping in-between shifts, which it's never done before....

It's not a tune issue. you most likely have a dirty MAF. Get some electronics spray cleaner and clean the little wires inside and you should be good to go.

Did that when it was all apart. And I didnt even re-oil the filter.

i thought popping was kinda cool. or is that backfiring? idk but you always hear cobras doing it when slowing down lol man im waaaaay off topic.

i want to port mine but ill leave it to someone who does it often. im worried i might mess something up then need a new one then need a tune
