142 is a good number on a Dyno that's not correcting. They all read a little different , what your looking for is the differenceYeah I'm calling bullshit, kinda like bikeman trying to claim the stock axys made "142" or whatever just so when it makes 158 it's this huge improvement. When dynotech Jim puts it to the test I'll believe it then
The point I was trying to make is the pipe makers tend to exaggerate the horsepower improvements of their pipes. SLP claims 9 horse, actual 4. Bikeman claims 12-13, actual 8, and the Aaen pipe made a whole 3 horse more. I'm just a sceptic. I'll believe the numbers when it's backed up on an independent dyno.142 is a good number on a Dyno that's not correcting. They all read a little different , what your looking for is the difference
