?'s about fmic install
I installed a fairly small trust core with 2 inch piping. and now my car spools slower (expected that) AND is just plain slower. Also, either my bov flutters or its my wastegate or my compressor surging. its not a normal flutter, it sounds like a clown laughing (woop woop wooop wooop) Should I get bigger piping? is my wastegate screwing up, my bov malfunctioning?

Something is not kosher with the BOV.....
Did you buy the IC used??? (ie is it flowing properly,,, sounds like the IC is creating a pressure differential)
and is the BOV before or after the IC??? (should be after, as close to the t-body as possible... I know cause Mines about three inches from the turbo, and I get some surge at light boost changes.. Gotta make a new pipe...)

Ok. bud.. sounds like you got the same problem i do.... boost leak somewhere....
I had my system apart the other week to seperate the fuel lines to supply each rail seperately, and, somehow, when i put it back together.... I gots a boost leak...
I can hear the turbo SCREAMIN all of a sudden and its Laggy and it aint got as much powah...
This has happened before.. 1 time I ripped the gaskett, another time once of the couplers was torn just a bit...
Gotta get that fixed cause the turbo will over spool and that can cause big time problems i a short time.
Like for i'll fitting couplers, loose clamps.... ETC..
Aslo... the Stock BOV can't take boost much higher than 8 PSI.. If you have it vented to atmosphere... I'ds seriously think about getting another!!!!

Ok, I'll really start cracking down on vac/boost leaks. I did use the home depot method.... ABS plastic most of the way, although every peace was glued inside and out. I'll re-glue and tape the outsides of all the connections.

I thought I had a major vac. leak coming from my stock TMIC's lower 'elbow' (to TB), so I went to home depot to find something... Well, they had a piece in the plumbing section that was the EXACT same dimensions as my stock IC elbow! It was a thick flexible rubber with clamps for $7.
Turns out, after putting that on, I still had the major vac. leak... So I just left it on the car.
A couple days later, I was racing a silly Honda on the freeway (you know, where you slow down and speed back up repeatedly, while they're going WOT the whole time) and as I went to pull away for the final time, my car suddenly lost power at 7k RPM's in 4th... I shifted into 5th (WOT) and it fell flat on it's face. I pulled off the freeway, turned around and drove home, staying out of boost.
I assumed I had popped off an IC hose or something, but I thought it was hilarious that after removing the IC for inspection, I saw the Home Depot elbow (had forgotten it was there) and there was a HUGE tear/blown out section in the side of it! I can just imagine the thing swelling under the boost until finally exploding, lol!
Moral of the story, avoid using Home Depot products for your intercooler needs, lol.

do not use homedepot cuplins!!!! they dont work... ATleast if you are going to use them, try to do so on the colder parts. Dont use them on the turbo directly nor the charge pipe. I would check the couplins.

I've been using the 3" to 2" coupling for my tid for over a year until now. and now its just a 2" to 2". Bcool suggested it may be the flexible exhaust piping i used to route around the battery and coil. Could this possibly be unfit to hold pressure?

LOL.... Boost... Vac.. its still a leak... only, I've found that with the haltech... vac leaks dont cause a problem if they are after the t-body... so, I always say "boost leak" because thats where I notice it!!! hell... When my one coupler ripped (i'm pretty sure the screwdriver slippage is what caused it).. I was driving around for like three days until I finally got on it real hard and noticed that there was a high pitched scream and only 11 PSI of boost in third..
I even had to do the old carb cleaner spray the pipes method to find the leak cause it was samll when not pressurized and on the UNDERSIDE of one of the couplers... right were I hit it with the screwdriver and thoguht nothing of it a few days before...
Back when i had the stock setup.. DAMN... any little leak after the AFM would wreak HAVOC!!!

Intercooler piping is what? Aluminum? Steel? Aluminized steel? Its used for exhaust and what ever else you want right?
Black ABS piping is used for what? Sewage? The ever popular potato cannon? I know several plumbers and worked with several at one point and even though it says it can take 600psi, and withstand a higher temp, they never trust it past 10psi and anything over 160degree conditions. Heck I can get out my heat gun and melt that stuff without trying. (Warning: it gives off BAD fumes when heated/burning, lethal ones. It should never be used moving heated air.)
Thats your problem. Plus it dosent even looks like you used the correct glue for it?
