So last weekend I ran my ski against my cousins. Both 06 rxp's my ski has a rr drop in wheel, his is bone stock. We both had the same amount of 89 fuel and I could walk away from him at any speed and was running about 2 - 3 mph faster top end. This weekend he filled up with 93 and me 89 (2 different gas docks). We swapped skis and I ROLLED him out on my ski. My question is how much timing can the ecu pull out? For example a 1.8t VW motor can pull around 12 degrees of timing out.
