I will break the 270 RWHP barrier if its the last thing I do. The good thing about the last 2 items, the pulley kit and the ECU tune is that their gains are relative to what you already have. The Pulley kit doesn't so much give you power as much as it reduces your power loss to the wheels. The ECU tune gives 20 hp to a stock N/A, a modded car will get more. My exhaust is also very custom and very extreme. If I can't get to stock SRT power levels, I can overcome the gear ratio very simply. Weight reduction. Every 100 pounds is a 10th a second. The driver has dropped 50lbs since July Lol's. Back to business, as you can see, my XF is not my daily driver. Practicality is meaningless to me. I still have a consolation prize if I'm not successful. All of those mods will transfer to any V6 or V8 later on when I'm older and have my career to fund this, so at least there's no way I'm wasting my money. At least I will be able to say I tried and stuck it through to the end. As for the 3.8 Genesis Coupe, I've lost interest in comparing myself to that as they aren't that much quicker than an N/A off the line, only about 1/2 a second in a 1/4 mile and they are well out-classed by even a base N/A in the top-end and handling categories. See for yourselves. G's on the skid pad, braking, weight, etc.

That thing may as well be a 300HP Civic.
