how much boost should i be making with a 2.9 whipple with a 3.5 pulley, arh longtubes, catless x pipe? im seeing 15-16 psi i was thinking i should be around 17-18.
I was having the same issue only seeing 15lbs with the 3.5. Put a 3.25 on, now its at 18. Wonder why this is seeing how others see almost 19 with the stock pulley.
What numbers you make?
I have no idea what the #s are, I'm working on a remote tune with Jon lund. I'm not sure what size the headers are, they were on the car when I bought it. It has a jlt high boost intake.
