Ok. Lets look at torque. The rotated 35r car hits 400ft-lbs by about 4700RPM and keeps going to 460ft-lbs while your car doesn't even hit 400ft-lbs. Also remember that you're comparing your road pull to my dyno pulls. On the road these cars spool a good 300-400RPM sooner than on the dyno in the same gear. I also highly doubt that you would hit the same power with more timing. Your system has significantly more back pressure which means you will hit MBT at a lower ignition advance. I could be wrong of course, but you can't just assume that you're going to pick up 50whp+ without trying it.
Again, I'm not knocking you or your tuning, just saying I'm not a big fan of the current FP turbos. Including the laggy FP red you posted that I tuned.
