70mm pulley for URD 2.7l kit

Anyone here running it on their URD/Rotrex kit? If so, are there any additional mods beyond stage 2 that have to be done? Also, anyone running meth injection on this kit?

Youll need some bigger injectors, or it might be possible to upgrade the 61lb 5th injector to an 80Lb version for more fuel. I know you can do that upgrade with the v6 7th injector kit, not sure on the 4cyl 5th injector though. Might call URD and ask, but thats additional tuning thatd be needed. Looks like boosted4 was last seen last year. Heres a pic of his post i saved. I think he has injector dynamics 1050x injectors

 

Gadget advised against it last we spoke.

This fella needed the same help as I with the tuning it sounds like.

 

As soon as HP Tuners has the 2TR tuning software available.

Or go to a much more adept standalone EMS, than the Map-ECU3. Even with the Map-ECU3, it will handle larger injectors.
