I also feel like the lower the hp the easier it is to feel in sotp
10-20hp on a 300hp motor is like 5-7%. I think everyone would notice a 5-7% increase in their paychecks lol
When dealing with 500 or 600hp, 10-20hp is like 1% and wont be noticed as easily, well thats my view on it.
Then again, thats if things are restricting.
