Re: BOSCH INJECTORS

A starter tune can be made with the injector constant changed. To finetune you would need to datalog imo.

Re: BOSCH INJECTORS

I didn't think you could fit 2.02 valves into the 305 bore. Or if you were able to get heads machined to do it, there would be no real flow gain due to shouding by the smaller bore?

It goes beyond just changing the injector constant
