So today i installed my 264's cams but the idle is really loopey and rough and stalls from time to time.I thought 264's idle like stock and wont stall,plus i'm getting what appears to be fuel cut,especially when WOT.I already turned down the boost a lot???!!!!
BY the way i installed a 255walbro too and tonight was a really cold night(-2 or something)might this be the reason for fuel cut?.
Any help appreciated.
Thanks.

 

check for the vaccum leak. I have 264/272. it has slight lope but never stalled once. It is all about the vaccum.

 

My car did exactly what you described when I had my cam position sensor turned 180 the wrong way. It's real easy to do.

 

oh, you should get the fuel cut if you are boosting too high with this cold weather. especially with 264 cams, your mid range power will be too much for stock ECU to handle. MAF reading on the ECU will be too high on that mid range and ECU will pull the timing like crazy then boom! fuel cut!

 

make sure you are not one tooth off ....

 

Thanks guys,i'll double check for vacum leaks tomorrow,i did turn down the boost a lot(hallman rx)and still fuel cut,What about the loopey idle,is this normal with 264's?

 

hey man, it's jay, who ended up installing? No tune yet right? Waiting for dynoflash to get here right?

 

That is very rare, I have 264/264 and I am very very happy in all aspects. Maybe retunning is needed

 

Hey jay,what's up bro? the guys at carz custom did.Pulls hard now but the damn fuel cut and stall issue.Yep waiting on dynoflash tune

 

damn man..... you making me jealous!!! When I hit fuel cut in my STI (cold weather & stock wastegate needed to be ported) damn, im surprised my airbags didnt go off haha.....

I'm glad Lucas worked something out for you.

 

Retune for sure.Hey fromwrxtoevo how was your idle after the install,i might have to check the cams part #to see if they really are 264's( i got them used)

 

Hey man, sorry to hear about your troubles with the cams. I advise you to not floor it until you get it tuned just to prevent anything from happening. Just offering some advice. Good luck man!

 

Thanks man ,but i've been flooring it since,just to test the fuel cut,i guess i'll stop now

 

M U S T R E S I S T U R G E T O H I T B O O S T!!!!!

 

i know man!!!
