750cc injectors

[freeman 188]

was wondering if I can run my 750 injectors on my motor without the dsmlink or do I have to get the car tuned first

You need something to correct for the fact that those injectors are almost 100% larger than stock.

so I might as well hold on to them until my dsmlink shows up and keep my 450 injectors in place

that would be a very good idea. you'll be pouring so much fuel the car will run pig rich and you could have some rich knock... dsmlink will take care of all of that though. best investment you can get for these cars!!

was wondering if my maft box can do anything for the 750,s it does have the switch for different size injector and now my car is running a little lean on my 450,s like 12,5 12.8 air fuel at wide open throttle ,

Yes you can use your maft to adjust for 750's.

Download the manual if you don't have it and it will tell you what setting to have it on for the 750's.

Patience is a virtue. Tuning with the MAFT is a total pain. Leave the MAFT on stock settings and tune with DSMLink when you get it. You'll be glad you did.

you might need to think about a 255 fuel pump and fuel pressure regulator with those injectors too because the pump might struggle, but that also depends on what turbo and boost your running. just remember that you need to keep your fuel pressure at 36.3psi and at higher rpms and higher boost with those injectors you may max the pump out

just goto my profile everything you mentioned I have already.

To heck with rich knock. With that much fuel, you will flood the engine right before it falls to pieces from fuel contaminating the oil. And anything but oil in the oil system is a .

OP, wait for link.
