Well when I go WOT I see pressure around high 900's for a brief moment then builds back up to around 1100-1200. Was considering going with PTP fuel pump internals to help get more pressure to the motor. Do these require a break in period? I was going to have the parts installed along with an inlet and upgraded intercooler if I do this and Dyno tuned the same day so I need to know if running the car hard that day is a good idea.
 
No, you cant do a dyno the same day as the internals install....period.

Theres a breaking in period, they say 100 miles of low boost and no higher than 4000rpm... It took me just over 200 miles to properly break in mine.

Good to know. I actually did a few pulls while out today and was in the 1400-1600 range so I actually think I'll hold off on the internals for now.
