I put the GTI on the dyno again on Saturday as I wanted to see if there was a difference after putting the colder plugs, the 4 bar FPR, and after a little time to adapt to the Revo programming.
Previously I got 177 HP and 222 ft-lbs on a low 70 degree f day on Saturday it put down 183 HP and 232 ft-lbs on a 90 degree f day.
The engine still gets mighty ticked off at around 4700 RPM when AF ratios drop below 12:1 and fall completely off the scale at 5500 RPM. Once that happens torque drops like a stone. I am going to assume that temps are getting out of line and the ECU is just puking fuel in to cool things down.
One odd thing though - power stays pretty consistant right up to 7,100 RPM - only dropping about 20 between 5,500 and 7,100 which makes me wonder how badly my stock exhaust is choking things.
I buggered up the disc with the runs on them, so buddy is sending me new data. Will post graphs when I get them.
