How to spot bad injectors?
 

I've got a 93 LS with a T3 kit on it and I'm having fueling issues. My timing is all the way retarded(as am I) and still around 9lbs it starts to detonate a little in 3rd gear. My current setup is:
Turbonetics T3
Vortech 12:1 FMU
340lph intank pump
MSD coil
DSM cooler
STOCK injectors
It detonated just like this before I put in the pump hoping that would cure it but no luck. Thought maybe fuel filter, nope. So my question is, is there anyway to check for bad injectors? I know it's possible to run 9lbs on stock injectors cause me and some friends have done this for a few years now with no problems. Any Ideas? Thanks in advance. :-\

9psi on a fmu?

u risk blowing yourself up also.

I'm ok with that too. :o

sell the FMU and get a SMC+(afc if you have the funds) and 450's and chip your ecu. Just my 2 cents.

Why would I chip my ECU? What does that involve?

well the chipping is jsut for timing issues because the AFC hack advances our timing. Some people use a BTM (MSD's boost timing master) which will retard timing under boost although i am still resolving the problem of advanced timing at idle.
