changin injectors?

[htownhatch]

Right now i have precision 1000cc injectors, if i change to a different brand but the same size injector would i need a retune? also if i just replaced the injectors with the same exact ones would a retune be recommended?

Thanks

IT all depends on if they have the same dead times and flow rates. You should make sure it is running safely before you really get on it.
