Is your 7 port stock? And what restricter are you using? I havent ran mine yet due to the weather and my PTM 5 port I ran it in truggy last year so I know I am going to have alot of tning down to do. I am going to start with the 7mm restrictor and .9 springs and if its still too much I will go to the 6.5mm and worse comes to worse go up a tooth on the bell but I dont want to have to do that.
