it depends on how u define the terms.... i guess a lil jerky just not smooth power

 

If it still has the Hetv valve in it, it will be jerky around 3000 rmps, which is where the valve makes its first turn. I believe it makes another to full open at around 7000. Look in the 929 section, they have a sticky on eliminating the hetv and flapper. Doing that WITH a PCIII and a custom map (dyno tune) will make the power band much smoother, the modifications to the flapper and hetv are EASY to do. Its all on you though. It works well with a custom map and the pc3.
