this is the second time this has happened to me both in cold weather...
was taking off (wot) from a toll booth and all the sudden at around 4-5000 it cuts out almost like a rev limiter .
dont know what it may be possibly runnin very very lean ? mods are tbe,o2housing,uicp,ntake,aps dual vent,NO TUNE YET ,lc-1 not hooked up yet

any ideas?

 

I know that when the car has not warmed up yet it may do this to you. Was the car on for a while already?

That or you could be hitting a fuel cut.

 

a tbe and o2 housing and intake without a tune? and no boost controller?

could be overboosting thats leading to the fuel cut

get a boost controller and turn the boost down a tad bit...if that doesnt work get a tune

 

no tune yet! you're hitting boost cut. You can even hit boost cut stock in cold weather, but with your mods - i'm surprised you're not hitting it all the time. do you even have a boost gauge?

 

na both times i had been driving for a while and it was the first time during both trips i went wot through both gears or at least tried both gears (2nd-3rd)
maybe boost creep ,i got a cheap boost gauge that sometimes says im boostin at 25psi but im pretty sure its way off(p.o.s)

 

is boost cut another word for way to lean? lol maybe its not such a pos after all ,wow doesnt feel like 25psi
tanks!

 

its another word for "some internals are gonna crack/get damaged under this boost! i will shut off fuel now before your engine gets pwned!"

get a MBC..they are cheap...turn down ur boost to stock VIII psi which is 15 psi i believe and see what happens. if it still happens...get ur thing tuned buddy...i wouldnt do all those mods without a tune...my engine will just be asking for it.

 

Cold weather, your mods and no tune = boost cut

 

Sounds like "Boost Cut" to me... I had my first taste of it this weekend. W/ the cold weather ~ 20*+ cooler, I overshot boost by 4 psi... Not good! I had to turn her down.

I think it would be wise to tune for cold and warm temps. Seeing that boost fluctuates this damn much...

 

simple solution.

tune the car

 

Exactly! you need to get the car tuned...spend the $200 and get a tune.

 

dont drive WOT unless completely warmed up.. i got s huge fire ball one time haha
intake, exhaust,bov, need a tune

 

the cold weather will make you overboost especially with a nice open exhaust causing the car to hit fuel cut.

 

get a boost controller and lower your boost...get your car tuned before you blow it up...you shouldn't be beating on the car with all those mod and no tune

wastegate boost is 12 psi

it's closer to 18 psi
