Default turbonetics, feels like its gonna die out...

when im on boost at high RPM, and then i let go of the gas and step down on the clutch at the same time, it feels like its going to die out. RPM stick drops down to 300-500 for a sec or two, but it still manages to go back up to normal RPM idle of 700...it just feels like its gonna stall. Anyone having the same problem???

Im sure the piping clamps are tight. i think its the vacuum hoses--> the wastegate port brass fitting?? what is this use for?? does the long vacuum hose provided goes there?? Also there is a port on the compressor, im thinking these two connects together??

Im sure turbonetics missed some steps of instructions.

The port on the compressor housing goes to the top port of you wastegate. If you don't have it connected . DO IT NOW!!!. You need to get the car tuned, that is why it feels like it's gonna stall. The car goes rich when you do that and has to compensate for it rather quickly. That's why the car feels as if it's gonna stall out on you.

Occationally happens to me. Sometimes it backfires and it has stalled 1time. The tune is almost too safe - pig fart rich. I'm positive my install is solid. I'm going to get it tuned next weekend and will post results in my thread. It runs great, but the clutch is screeming for mercy.

It just needs a tune, or you can just slow the car down in gear before you sink the clutch. It's not good to go full boost in a gear and just sink the clutch and coast anyway.

u replace your spark plugs... munch im suprised u didnt say that. I had the same issue as you, just replaced the spark plugs (one step colder, NGK Iridiums) and the car is doing much better. I still have some crazy air fuel reading, running real lean just above 2000 rpms and gettin to rich for my taste around 4500-5000 rpms but nothing a lil octane booster and a unichip tune wouldnt help.

Even with colder plugs, if you are running real rich, it will dip in low in the RPM's and then muscle back to 700ish idle. Our does this, but we have the ZPI kit. It never stalls, but as Munch said, it's not good to be on it, and then coast after that. It's either "All" or "Nothing". If you get on it, then take it through it's passes. But don't play with the turbo's emotions.

You want to go one or two steps colder with a turbo setup depending on your tune and boost level.

Right I know that about going 1-2 down on a turbo, thats a given. But I think that what I said was a known fact.

I dont know, I read it somewhere... I've had a rough weekend lol...(friday night good times)

did and connected the hose to both the wastegate port and compressor port, still doing the same. But it helped a lil. Other than that, it runs good, no problems.

hmm, ok ill get it tuned. hopefully this time itll pull faster, cuz my gutted civic hathback with type-R motor was instant quicker, lol.
