Red Box tweaking testing and results

My car is a commemorative edition so I already had a std. red box APC which generated a max boost of 14psi and tapered to 11-12psi with a k&n and 3.0 bar FPR. Then I borrowed an SPG9 stage 1 APC box to try. 20+psi of boost, but feels a little tough on the clutch and gearbox and I have some fuel cut issues, so I wanted something in between. I opened up the red box and checked base setting for F and P pots. They were F=284ohms and P= 23,100 ohms. I tried a few settings and ended up at F all the way in (about 495 ohms) and I only turned P at bit(probably about 31,000 ohms). Results are great. Max boost is 16 psi in all gears. Taper back to around 13 in 2nd gear, but holds at 15psi in 3rd and up. Pretty happy and will save $299. I must admit the SPG9 box is great, but this is a good compromise.
I also just got my 16" aeros and Kumho 712's on the car. It looks and drives awesome. I will post some pics of my CE over the weekend.
