Trying to find out whether or not there is an acceleration / 1/4 mile difference between just a base 18+ A10 GT vs the performance pack level 1 / 2. Is it worth it to upgrade the base 300A to the 301A? Or is it something that wont matter once the vehicle gets tuned. Thanks for any input and...
What mods / tune did you go with? Wanting to hit close to 700 rwhp. At the moment I have a corsa catback / phase 1 roush kit and the roush tune. Whats the fastest route to getting power without converting over to e85? Wondering what everyone is getting in their 1/4 mile times as well. Thanks!
