injectors and fpr

[Zorin]

89 325i vert.
I have mustang injectors (19.5) and adjustable fpr.
I know it needs to be at 3.5 bar for 19.5 injectors.
do i need to have a custom chip made or can i use stock software ?
next upgrade i am working on is m50 tb.

19lb injectors are not going to cut the mustard on a turbo car.

agree. you should be looking at something like 300+cc injectors. Make sure to get a RRFPR as well.
