I love my ID850 injectors. I was using the LS9 injectors at first but when I saw my pressure dropping and the injectors were near maxed out, I knew I wasn't far from a disaster.

In all honesty you can get away with pressure trailing off a little if the injectors are oversize, and you can get away with injectors running near max if your fuel system keeps the pressure up, but being borderline with both is playing with fire.

500 to 550 rwhp through the auto is no slouch. If you just put in a BAP then make sure you datalog and watch pressure and injector duty cycle closely. I think your injectors and your fuel supply will both be about maxed out.

IMO I would at least do the ZL1/ADM combo. ID 850 injectors would be next. Maybe not a necessity at this point but the LS9's will be up in duty cycle and leave no safety margin. MSD can always be added in the future. I know it isn't cheap but you are likely not far from being maxed out already.

Do you happen to have a log of a quarter mile WOT run logging injector duty cycle, fuel pressure, and AFR? If you don't, all might not be ok!

A drag strip is the only legal and safe place to do a sustained WOT pull. I suggest that you go to a test N tune day at a track. You do not need to "race" anyone, just make a couple of passes (even solo) and log the injector duty cycle and fuel pressure. It would also be nice to see your shift points, timing, boost, and iat. I'm not implying that you ever do any WOT driving off track, but the power plant does not know if the car is on the highway or the track. It can also be damaged on the street if it leans out due to insufficient fuel during WOT.

thanks for your suggestion,,,,but the way my car is driven I don't see a need to go through all that,,, i'll trust the tune that dan millen put in my car... livernois does extensive tuning and driving of your car while its at there facility.

Without a ADM FPCM the ZL1 pump doesn't do alot more than the stock pump. Ill bet your pressure is dropping towards the top of each gear. OK if the injectors are big enough. 60's aren't bad. But for the OP, no sense in upgrading to just 60's.

I trust what livernois motorsports did on my car,,, it runs strong, but honestly on the street the power is unusable...
