2004 returnless, aeromotive 340, 500rwhp Would like plug and play injectors, and I'm going to be running a 2bar SD tune. Im looking for 60lbers

 

I have a set of ls9 injectors less than 200 miles on them the are 57lb i can get you the part numbers on monday if your interested they are at my shop

 

I think you'll still need either adapter pigtails, or the proper connectors to fit those ls9 injectors. If it's a 2004 truck set-up, it has the MultecII injector plugs.

 

Have you installled the Aeromotive pump yet? If not, make sure it doesn't outflow the stock intank regulator. If it does then your larger injectors are going to be extremely difficult to tune at idle due to the pressure being too high.

 

Yes it is the multecII style, no I haven't installed the aermotive yet and hot wire kit, do I need a new regulator? Also my tuner said it's best to get a flow chart with the injectors

 

Delphi - 62lb MULTEC II GM Supercharged 4.8, 5.3, 6.0, 8.1 - Fuel Injectors MOD Sets - Siemens Injectors & Lucas Injectors - Racing Fuel Injector Sets - 11167625 these are the ones I've been looking at

 

Will those injectors work for my application and what about the regulator?
