will 750cc injectors work with a rtek 1.7 ,,,,,,,because i read the rtek web page and they said atleast 720cc were fine but never said max...whos running a rtek

 

750s are fine

 

There is no max. But the Rtek 1.7 only compensates for 720s. Anything above that, you'll have to provide a way to lean them out.

 

what kind of aftermarket mod do you suggest for fuel leaning issues

 

Technically there's no maximum or minimum other that the limts of the fuel controller used. If you use injectors smaller than recommended you'll need to use a fuel controller to add fuel. If you use injectors larger than recommended you'll need to use a fuel controller to remove fuel. If you use the recommended injectors you won't need to use a fuel controller, but they're are always gains to be had from using one. It's really no different to using different sized injectors with a stock (unchipped) ECU.

There's only a 2% difference in total flow between 720 and 750cc/min secondaries anyway, so I wouldn't worry about it.

 

Im thinking about to use Rtek 1.7 and 1000cc secondarys.
Then I got a SAFC2 to lean them out a bit.
