I have an s5 TII with:
stock turbo, ported wastegate
racing beat 2.5in downpipe, presilencer, to corksport 3 inch catback
fuel pump
old school hks fmic
720cc secondary injectors
wideband

I want to run 12 ilbs at the most and i was wondering what rtek to go with?

Is just upgrading the secondaries to 720cc's enough for 12 ilbs?

 

I was starting to think everyone's car blew up. Its been awful quiet here.

A 1.7 with 720s would probably be fine if you aren't going over 12 psi on the stock turbo.

 

pffft, It's just the opposite, No One is having and trouble with their Rtek's.

 

do i need a boost controller?

 

If you want a way to control boost, yes. The Rtek doesn't control boost.

 

and one more question.. will i need an safc or somthing to control fuel? or will just having the 720 secondaries for 12psi be fine.

 

Depends on what you want to do. If you want to control fuel, you'll need an AFC or a stage 2. With your setup, you'll be good, maybe still a little rich, no way to know without trying it.

If you want to get everything you can out of 12psi, yeah, you'll need a way to control fuel. And unless you already own an AFC, the stage 2 isn't much more and you get a lot more features than an AFC.

 

well..do i NEED to control fuel with this setup and the 1.7.
