Hi guys!

Following question!

I drive an S4 1987...

i will smash a CAI on it, and also a full 3" custom exhaust from turbo 2 back without cats...

i know i'm going to hit Fuelcut!

So, i wanna buy a Boostcontroller, the Apexi AVC-R...

can i set with the AVC-R a boostlevel 0.5psi UNDER fuelcut and drive the car without any problems? will i have boostspikes which will force me into fuelcut? how much power @ flywheel and wheels i will get out of this setup?

also, when i have a FCD defenser later + SAFC II + portet wastegate, which amount of boost can i drive with the stock TMIC + stock injectors?

later then, when i got my warlboro pump + rtek1.7 + 720 secondarys, what's the maximum boost i should drive?

 

i had hks intake and just hollowed cats when i first bought my car and still hit fuel cut so even if you set boost low it will still hit fuel cut

 

why would it hit fuelcut with an Apexi AVC-R set 2 a fixed amount of boost underneath the fuelcut?

high spikes?

 

with just a boost controller your still going to hit fuel cut because of the unported wastegate. you might as well just get all the mods at once. I didn't and got a little heavy on the foot and needless to say I walk to work now.

 

so i definitly need to port my fu**ing wastegate before i install a full 3" turboback?

 

^yes...

 

I'd atleast get and rtek, why are you in such a rush to pop your motor? Running the stock turbo, I would never push it anything past 12psi cause the risk outdoes the gain without question.

 

ok, so i have to port my wastegate... and i so have to pull my turbo... and so i'm waiting for my project engine before doing the full 3" exhaust

@ gerbradly

why i have to get an rtek if i have my boostlevels under fuelcut with AVC-R + SAFC II ?
later on, when i turn my boost up with the new engine, i definitly will go rtek + secondarys! and some times later FMIC + passive CO² cooling...

 

PORT THAT WASTEGATE.

it'll make the car/way/ faster anyways.

 

your wastegate determines what your lowest boost setting will be. If you push 12 psi without a boost controller...then that's the lowest you can run WITH a boost controller...the controller is only to turn the boost up. So port the wastegate. Then you could try to push up the boost a bit. If you can afford an avc-r...you should be able to afford an FCD. I'd buy the fcd before the avc-r. You'll won't need to turn the boost up until you get some more fuel mods.

 

with 3" and cai you'll be hitting 12psi for sure without your WG ported. I ported my wastegate as big as the stock door would allow, I have 2.5" turboback straight pipe, and 3" intake and I hit 9-10psi daily. You *WILL* see some nasty boost spikes which could be detrimental to your engine.

 

i dont want to **** up my old engine, and also not my new engine with spikes?

what the best way to drive with the lessest amount of spikes?

i think i know the answer... EMS, singleturbo + external wastegate :/

 

No it won't. Why would it?
