I"m currently running 550 pri and 1000 sec with a microtech lt10s,

Staging comming into boost ~2", 2psi is pretty bad, AFRs dip into 10-11. I tried leaning it out so that it wouldn't but then the staging is more 'pronounced'.

I guess the problem is that since my turbo spools so quickly that i get boost nearly all the time under very light throttle.
Proposed solution to be was to run identical injectors in primary/sec. SO I'd be going to 1000/1000.

But then comes the issues of tuning the 'idle' which I don't have a problem with or see as a problem.

I see alot of setups with 720 pri and 1xxx secondaries with no complaints like mine but I'm assuming they don't care about the rising cost of fuel :P

 

um why don't you just tune the ecu?

 

I can't remember about microtechs, what is the RPM increment on those? What about trying to stage the secondaries a little bit later in boost around 5-6psi?

 

Those are small injectors and shouldn't have any problem with a proper tune.

Stock FD are 550/850.......

I personally run 850/1600 on a daily driver and you can't tell a transition.

It's something you just need to work on with a tune. WOT tuning is for amateurs.

To get a car to run like stock is what seperates the men from the women.

 

Microtech's are notorious for having poor injector staging resolution. But with that small a gap (my 550 / 1680's are a little tougher ) You should be able to get it pretty close
