fpr shim?

[black_cloud_stroker00]

I was thinking about doing this mod? However, I have a 140hp TS Performance chip. Would shimming the FPR be redundant because of the chip? I talked to TS Performance and they said the chip does up the fuel pressure, but they did not specify if it was the the fuel pump or injection pump. any advice?

I don't know who you talked to at TS but it must not have been Dennis Perry! Chips don't raise fuel pressure.

READ HERE for a thread with more explanation. BTW, we don't have an injection pump.
