I have 2011 gt500 running no cats with stock mufflers,jlt 123 intake, Atco heat exchanger, sct tuner, tr6 plugs, 170 thermostat, looking to put a vmp charger on with 65 duel plate throttle body and a 2.4 pulley. Not sure what injectors to run. This is a street car looking for great drive ability and reliability. Looking for some help and suggestions. Thank you

I believe the stock injectors are 47-48lb 07-12 GT500, 55lb 13-14 GT500, the 47-48lb injectors would be maxed out running a 2.4 pulley on a vmp TVS blower.

You could maybe find some 13-14 Gt500 injector for cheap, but you wouldn't have much room to grow, I would get some Injector Dynamics 725cc or 1000cc injectors, they are not cheap but they are easy to tune & you will not have any drive ability issues, just go ahead & get the 1000cc if you plan on making more power done the road, the 725cc & 1000cc cost the same.

DO NOT BUY some off brand name injectors or reflowed Bosch injectors, there is no data to tune them correctly & the car will not run right, stick with ford racing or injector dynamics, they have all the data available to tune them correctly....ask me how I know

Injector choices

I have looked into those injectors and they run about 950 for the 72 or 100. But the ford racing 60 and the 80 are a lot cheaper 400. And stock 13, 14 run about 200. I think the more expensive injectors are probably better but what drive ability concerns can be caused by the 60 or 80 ford racing injectors cause?

I've been running SD 80's for a few years. I believe at the time FRPP was using rebadged SD injectors. But I've been using FRPP values with no issues. I can't really complain. I even used them N/A for a while.
