All you need is a Torque Converter, a custom tune to get rid of the fuel De activation and bump up your timing, then you will be beating up all them six speeds all day long....at the track and Automatic car always has the advantage.
I have three toys...
1-06 GTO A4... 556RWHP 508 RWTQ. high 10's 1/4 mile....CCW Drag Pack.
2-09 Z06 6 speed.. with just headers and a halltech CAI custom tune..508RWHP 492 RWTQ. high 10's 1/4 mile. CCW Drag Pack.
3-11 CTS-V Coupe 6 speed super charged.... custom tune and a pulley swap, 550RWHP 600RWTQ. Low 11's 1/4 mile. Drag Radials.
The Manual LS3 cam has more lift and duration than the L99 auto due to the AMF system. It makes up for it with the VVT system that gives it more TQ at lower RPMshi, does anyone know why the ss stick puts out 26 more horsepower than the automatic? someone told me the exhaust is different is that correct. thank you in advance.
That article said the automatic is rated for 25 mpg on the freeway. I have to toss the BS flag. I just finished a 900 mile interstate run and the best I could pull from my auto SS was 21 mpg. Now, I found the DIY article about resetting the fuel maps in the ECM to gain a few horses back...will the lower octane fuel maps also lower mpg's?
When I reset my fuel maps with the fuse pull trick it helps with mileage and performance probably because it is much more efficent. I have to do this about one time every month or so because I live in a county that is classified as "non-attainment" on air quality and our fuels are classified as "reformulated" which means it has a 10 % ethinol mix.
If I drive to the next county that is not in the same class then I purchase the normal fuel and it is much better still and I do not have to do the fuse pull. Even my '99 K1500 4wd suburban get much better mileage with the regular fuels.
I found that buying the octaine boost for 4.99 per tank is better than driving 45 miles to the next county unless of course I'm already heading that way.
Still use Shell V power premium as always but it is much better in other counties.
I'm worried about my mpg if it is supposed to be getting 5 more mpg than it is. Loss of mpgs can be attibuted to mechanical issues, and in a new car that is significant. Loss of mpg indicates a loss of efficiency in the engine. I want to know is it a real loss, or is it that everyone here on this forum is getting the same mpg that I'm getting, meaning there is nothing wrong with my car (or everyone is having the same problem!).If you are worried about mpg then you should of bought the V6. My car could get 10 mpg and too be honest I really could careless. I swear most of us don't even get pissed at filling her up compared to a guy who's driving a 98 Civic and spending money to gas that pos up.
