Those with Helix IC piping

Anyway...I forget but does the helix kit have an intake? If so did you run the stock airbox before and are now running an intake?

nope no intake....stock intake piping with Apexi intake kit, have always had that on there. That is fine. Intake would not be the culprit either.
no the kit does not have an intake.... you made sure that you connected your boost line correctly on the turbo outlet pipe? i installed mine directions in the HOW to and i have yet to have any issues and felt quite a big change for the better and have yet to b tuned either... going in a week.. lemme know if i can help any
ah im custom tuned, so that should be fine, was told no retune would be needed. Yes boost line is hooked up. Even put teflon on that fitting and tightened down, and always use zip ties on those lines. Peak boost still seems to be the same. So i dont think that is the issue.

yes, this is what i seem to be leaning more towards, but i promise I checked all of the couplings, clamps were all tight(actually very tight when done, i always seem to over tighten). I was all excited to hit that 300mi breakin on that clutch, and now its nothing i wanted to even feel.
Reset the ECU. I had the same initial impression after I put my helix IC pipes on. After I reset the ECU, the car felt much better. Also, have you checked your boost? Make sure you're hitting the same amount of boost as before.
I'd pressure test the intake to make sure there are no leaks. Just because your hose clamps are tight does not mean there will be no leaks. It can still leak if one of the couplings is not set right.

yes I was boosting same PSI, ecu was reset during clutch install. Today i was boosting same PSI all day,but it felt really weak. Only one time up a hill did it feel really good, and now i am just hitting 17-18psi, when i usually hit 23lbs, so I know for sure I am leaking somewhere now. I took the front bumper off tonight and checked the ones at the intercooler. Took it for another spin, nope no go. 17-18lbs still...Grrrr...this piping sucks.
I just ordered a bunch of stuff online and after reading this thread I canceled my Helix lower ic pipe kit. As much as I want one I dont think its going to benefit that much on a stock turbo and its not really worth the money right now with my current mods. Ill switch to a larger ic pipe together with my fmic later down the road.
The only way to be sure you don't have a boost leak is to pressurize the intercooler piping and spray some soapy water on all the joints/couplings with a spray bottle. Look fo bubbles. you might be very surprised by how much it is leaking.

Without a boost leak it fails me how such problems can exist solely due to the piping in itself. With slight variations to design, it all serves the same purpose and is executed by the same means. I dont see how the piping can just be writting off as "sucky". I thought it was a volume issue, but there is clearly a boost leak.

well guys, went at it again all day today.. This time made a pressure tester and used some soapy water. Sure enough found a boost leak at where my boost gauge is connected to the manifold. Did not find any around couplings. So i fixed that one at the T. Just now took it out again to test it out. 17-18psi ...WTF??? im wishing now I woulda just kept the stock piping on the stupid thing. ...so ok, maybe i am stupid and just need to turn my MBC up some....ok got out, cranked it up some....test it again...17-18psi. WTF?? Im stumped on this one. Other than that one leak i couldnt find anything. We couldnt pressurize it anymore than 12psi today and this was the only leak we could find. I dont know where else to look. This crap just makes me want a Supra even more. (i know i know, they will leak too). BTW we pressure tested from the beginning of the lower IC pipe right after the turbo discharge pipe.

Well, I put my Helix IC pipes in last night. My car doesn't seem to be any faster or slower than before. Boost dropped a little, but I fixed it with a slight nudge on the ole' MBC and now it's back up to where it was before.

that or something else is up from the clutch install.
