Hello all,
I recieved the Scorpion 1.7 RRs yesterday. Do you think I need another pcm tune for them. I know the car is running a tad bit rich right now, will the higher lift lean the car out.
Heads flow 269/191 @ .600 lift. ( I wanted good mid lift #s over peak.) New lift will be .578/.590
Do you think it will be worth it. If not I'm sending them back to FLatlanders.

You should run OK with the present tune, you'll probably still be a tad rich , but you just never know fully how they are gonna react.

 

Thanks for the input,

We will see what happens.
