choking KAT

[rb26iwish]

my ka24det seems to be choking i have a good idea of what it is(not enough fuel pressure i dont have it regulated yet), but just need some feeback to validate my opinion. At "WOT" my 240 is fine but for some reason from idle to about 3000 rpms it seems to sputter or choke after 3000 rpms it is perfectly fine well that is until it hits 5200 rpms its rev limit? but thats not even the stock limit !!! ,and my ecu has been tuned by efi specialists and it was raised so if anyone has any ideas get back to me

I hate to say this, but take it back to the shop man.

If it's fine at WOT, you have enough fuel...A 5200 RPM rev limit doesn't make sense either.

I think you have several problems here, the first and biggest being a boost leak.

You WILL get more answers the more grammer you use. Please.

oh man a boost leak great well thanks i really appreciate it another thing i noticed today is it doesn't read boost the is vacuum at twenty but doesn't go in to boost it stops at about zero does that indicate boost leak? thanks for your help

If you're not building boost, you have a problem. Finding any problems with boost leak is a good place to start.

What type of BOV valve do you have? Is it just venting under every condition?

Are your vacuum lines hooked up your turbo/wastegate/BOV properly?

There are a lot of possible problems. I'd check vacuum lines, BOV, and for boost leaks.

We can't fix your car for you man, only lead you in the right direction...Good luck.
