As everyone that already has an A5 probably already knows that the A5 is a beautiful car but lacks certain things that other competitive cars have. BMW, Infinity, etc have slightly more oomph(horsepower). I bought the A5 because it was only a 6 month wait compared to the S5's almost year wait, at the time according to the dealership. I always loved V8's but the way the gas prices were skyrocketing I thought it was a better choice to get the A5. I have an A5 S-line fully loaded. I figured at the very least, I would add some aftermarket parts to get the power up to where I would like it. These cars also have to be up in the higher rpm range (3500-5000) in order to feel the power that it does have. I don't think the car is by any means slow but it just feels like something is seriously holding it back from it's true potential. I was wondering if anyone out there has done anything or knows of anyone or anything that would bring the A5 up to it's full potential. I know that the new S4 has a 3.0 supercharded engine but had done a lot of research into a company called STS (Squire Turbo Systems) and they have a really good product, just not for Audis. I truly feel that if this car could get the horsepower and torque of the V8 S5, it would be an amazing vehicle while getting better gas mileage and being lighter and better handling.
