I have a couple questions on the PHP order form.

Under Modifications on the second page at the top where it says:

- Current Displation
- Comp Ratio
- Max RPM

If I am stock do I still need to fill this part in and if so would the information be in the trucks manual?

The only mod to my truck is a K&N drop in and the 3" PVC change on the end of the air intake to the fender.

Sorry I'm more of an electronics guy then a mechanic.

Thanks guys!

 

I left that part blank on my order form and my Grpyhon is fine.

 

just write "stock" on it somewhere and skip the questions.

 

^^ I can do that.

Thanks.

 

Make sure you put in 4.6 or 5.4 in current displation and stock in the other two.

 

Ronix, what I always tell people is that if you didn't modify it, just leave it blank.
