Currently I am procharged with their booster pump setup with an uprev tune.

I have gtr injectors to drop in because i want to eliminate the booster pump. I dont like watching fuel pressure go well into the 100s to keep fuel in check.

My question is if i plan on eventually ls swapping this would you add the return system or leave it as it is and just put in injectors and retune for them.

 

If the LS you're swapping uses a return system, go ahead and add it now. If it doesn't, don't bother.

 

i havent picked one out yet so i can just save the fuel setup if thats the case. Although i wont need the AN rails i have either way IF i dont put the system in now
