Running HD stage 3 chip with 550s instead of 444s

[Nicksemianiw]

What do you guys think about running the Horsham Developments stage 3 ecu chip but instead of running 444's if I put in 550s and just did fine corrections with a SAFC-NEO on a dyno. What do you guys think? Or would it not run that well? Its casue the only tuner in my town wont take my injectors past 85% duty cycle and at 85% on 444's I wont make my power goal of 270whp. maybe only 245-250. Im running a S14 T28 if that helps lol.

Email horsham, im sure they could send you a proper chip for not very much.

Yup, I would email Jez and ask him. I think you should be able to do it, but you'll be very rich until you fine tune with the AFC.

This guys is running 444cc and dual pumps on HD stage 2 without issues, and that chip is supposed to be used with factory 370cc injectors:http://www.sxoc.com/vbb/showth...43884
