I have a 2003 Z with 20G GReddy TT. 440 injectors, turbo back exhaust, HKS EVC I do not have piggy back yet. It still has the factory ECU. I know that UPRev makes Osirus. I also read about Cobb Accesport. I know the accesport is discontinued, however there are company still selling them. I want to run about 8 pounds of boost. Can I use the COBB? Should I? What piggy back EMS should I use? I need help... Please...

 

Do not use the COBB.
You really don't need the EVC.
Depending on your area and local tuners I would use Osiris, or if you have to get a UTEC as it's easy to tune. If you are looking for a full EMS going with Haltech.

 

If you are looking for something to get you by, the Osiris reflash will work with your 440cc injectors. If you are looking for a good ems that will grow with you, I would recommend a Haltech plug&play standalone. If you do the Haltech, go ahead and install a larger set of injectors such as ID1000s so you don't have to retune for injectors if you decide to turn it up down the road. These will provide plenty of fuel for your needs, and I can tune them to run like stock with the Haltech. The 440cc injectors will restrict your max power output, even on a stock motor. We are in Lexington KY, only a couple hours from you... give us a ring to discuss options and we'll get you scheduled on the dyno 859-230-9027
