Taking out your old injectors, putting the new ones in and tuning with an safc or similar. ---

These would be the same style of side feed injector as the stock ones on my SR? Would it be nessesary to tune with a SAFC or could I run these with an upgraded fuel pump without and ECU mods? just stock… Anyone know what all I would have to do to run upgraded injectors and fuel pump? Depending what all I would have to do to make this upgrade work, I would be very interested in these! I am not looking to push the 300HP barrier, and I have heard the stock ones can reach that, but that they would at their max, so I would like to go with a samll upgrade like these. ---

If these are top feed then mounting them up would be much harder then just putting them in. One would have to rig up some custom fuel rail. So… thanks, but no thanks. God luck with the sale. ---
