DSMer question(HELP a noob please)

[spadepro22]

I got a hard intake pipe install today, and now the car run like crap around 5-6000rpm(backfires and seems like it dont wanna go). Should I just hook up my old rubber piece and call it a day. It ran perfect before the install.

 

[spadepro22]

I put rubber pipe back on and it runs great again. I dont get it, whats the problem. No hoses like before and it runs great. Maybe there was a leak, but dont know how with no hoses connected.

what do you have to tune with? maybe the old rubber intake had a split in it and was tuned that way and now the metal intake does not leak and it through the tune off.

Why is only one person here suggesting a boost leak test?

If its a boost leak, it should be between the maf and turbo right(no other hoses connect). Could be the cheap plastic that ebay supplies? Thanks guys

No, it doesn't have to be there. What could be happening (along the lines of what blkgst97 said) is you had a boost leak and a vacuum leak on the rubber snorkel canceling each other out on load.

Just do the test.

Does the rubber snorkel have the ports for the vacuum hoses plugged? Does the new intake have them plugged? Are you getting a good seal on the MAF > Snorkel coupler? Snorkel > Turbo coupler?

Rubber and hard pipe hoses were plugged. I hooked back up the rubber and its fine again. The hard pipe, not so much

Recirculate your bov.

 

[kornfedgsx]

look at the fitting how they fit compared to each other, check everything that could leak on it.

Im still in question of the form of tuning....if its not dying off throttle without recirc it must have something.

 

[russ96gst]

^^^not always true, when I was young and dumb, mine wasent recirculated for a while and it never died, and I had no sort of tune, actually thought it ran fine, that is until I did recirculate it and I ran MUCH better, but as others have said just because you say it runs fine...fix the BOV and recirculate it, and do a BLT!!

 

[91mitsuman]

Ok I see your running dsmlink v2. Did you do a log with stock intake and 1 with the hard pipe like was suggested earlier. See if anything pops out. How are you plugging the holes on the hard pipe vs. How they ar e plugged on the rubber pipe. If the hard pipe even has provisions for them. Have you done the boost leak test that has been suggested by many people.have you tested the maf or check the readings from the maf on link. Pictures, logs and where you are at will help us to help you.

He is admitting to not running his blow off valve recirculated then admitted it runs fine when he put the tube back on. Clearly he is an idiot that won't listen to other peoples advice and logic.

His car is running like shit because the blow off valve isn't able to work properly. Not having it recirulated is the reason why his car has a boost leak in the first place. The reason why it's worse now than before is the hard piping isn't ballooning.

Spadepro... post a pic up, that would help alot...

Do a boost leak test right this second!

You're right, but he didn't say that he hooked the bov back up and it worked fine, what he said was that he hooked up his old rubber intercooler piping and it ran fine. But yea you definitely need to recirculate your bov, and hook up all other needed lines and do a boost leak test, no matter how fine it runs with rubber line and bov unhooked.

Wow if you read my post you would've seen the bov wasnt ever cirulated with rubber or hard piping and my car dosent run like shit with uncirulated bov(runs like a champ), only with hard pipe at about 5-6000rpm. Boost leak came from the cheap plastic that came with intake pipe.

Cheap silicon coupler you mean? So you got it taken care of? That's good.
