I used the 175hp tuneup today and those are the best figures. That is right, the 175hp tuneup produced 226.9 additional rwhp and 304.9 additional rwtq.
Using my conversion factor, that equates to 1109.9hp and 1104.0tq at the flywheel!
Needless to say I had some problems with the tires spinning on the rollers but I got that figured out. All of my data from the Racepak data acquisition system looked really good and the spark plugs were perfect.
My system has 4 horsepower settings, 175, 200, 250, and 300. My next test will be with the 250hp tuneup. This will happen tomorrow sometime....
