Hi everyone,
I got a question. How many PSI should I be pushing completely stock. I installed an Autometer guage and I am pushing around 16 peak. I bought the car used so I don't know if it's modded somehow or the guage is off or what's up? Help me out.

 

Thats alittle high for stock, does it stay there or just jump up to it then go back down to around 14 or so?

 

maybe 3/16ths mod was done. but i doubt it would go that high if it indeed was done. mine only goes up to 14

 

i got mine at 12.5PSI.

i know that stock fuel cut off is 13.7, so i run that psi to be safe.

 

I did the 3/16 mod from boostkits.com and my boost is now at 15 and it gets up there alot faster and stays there a little longer.

 

I took it for a more thorough drive today and it peaks at a smidgen over 15 and settles at 14.
Thanks everyone

 

What is this 3/16th mod?

Its this http://www.scoobymods.com/forums/sho...?threadid=1564 but I wouldnt suggest doing it. It can cause boost spike and I (like many here at I club)took it off after trying it.
