I am running 50# MSD injectors that I bought form 9secondlx and I installed them and reflashed the PCM to 42# and I have 55psi fuel pressure...

What is wrong here???

offsets?? I used the 30#svo and now the stock and no change...

I changed to speed density to verify if it was an intake leak and blms are where they should be... The problem is that thet should be 50# and I first reprogrammed for 52# since I was running 58psi and the car was running extreemely lean...

Is there any way to differentiate 50# from 38# msd's?

Let me know

Thanks

 

What's the impedance on the 50's?
