Curious as to how much timing advance you were seeing tapering to 25psi. I have been dialing in my tune and believe targeting is to blame for my moderate timing advance. I know W/M would help, but not quite ready for that one (ok maybe I am...).
Would the fuel pump upgrade be beneficial if the car is running an IS20 and 93 oct only, no E fuel?
I'll let you know soon. I'm going to that and injectors. Mostly for ethanol use, but also to lower trims all around. I'm going to do the hpfp first to see if it does anything at all on its own, then the injectors after.
100k?! I'm almost about to hit 30k...
damn... golf r injectors are expensive lol
