hey i want to know the simplest and cheapest way to improve horsepower for my car. i already have cool air-intake, bi pipe, exhaust from the cats back. if anyone knows some easy ways to improve horsepower that would be great. thanks

 

chip

that is all

 

tell me what is the difference between stock and when it chipped besides its faster

 

Stock 2.7T is 250hp and S-line is 265. A chip from GIAC, APR, etc will generally get you to ~318 safely. In addition to the chip, you should upgrade your diverter valve and throttle body boot which could leak/split under the higher boost. It you have a tip - beware - the additional hp can cause tranny problems. In my case, I had to replace the clutch/flywheel about 10k miles after chipping. It could have been due to the PO doing light towing, or that 150 mph run and another weekend run of WOT and 70 to 120 mph sprints. Whatever, the clutch started to slip and I replaced it with a stage 2 and no problems for the last 120k (206k on the odo).
