Grrr. Diesel shop set my injectors too high. Problems?

I bought a set of injectors from a board member. Smooth transaction and the injectors were in good shape.

However, they were from a turbo car. The pop pressure was stamped in the housing as 135 bar.

My W115 calls for a pop pressure of 115 bar.

I dropped them off at a (relatively) local injection shop for cleaning and specifically stated to set them to pop at 115 bar +100 psi, so that they "settle" back to optimum pressure over time, instead of dropping below.

It never dawned on me to double check with the tech while I was at the shop (100 miles away). So I called today to ask and guess what they were set at?

"What it said on the body plus 100 psi"."

We're taking her on a 1,000 mile road trip over the holiday weekend and I probably won't have time to get the injectors back to the shop. My new Bosch remans are ok (India and ~4,000 miles as per PO), but one has recently developed a slight fuel leak between the body and the lower section.

Any problems with running these overly sprung injectors or should I soldier on with the Calcutta Cheapos?
