Ever since I had my timing belt done and the IC pipping removed and reinstalled there has been a boost leak.. I've taken the coupler out and replaced with new and same with the hose clamps... Still boost leak... I think i Have those ebay IC... So the hose is in many pieces so more places for it to leak...
 
Anyone know of reason place I can buy new better piping? Similar to twosrus? I noticed they have 2 pipes rather than 4 or 5 pieces I have... 

take your intercooler to a radiator shop and they can put it in a tank and see if its leaking - I had my previous intercooler re-wielded and was like a $20 fix....
 
how do you know there is a boost leak? your gauges wont be accurate for a little while (few drives / runs) after you put it all back together cause the pressure / air line wont be pressurized
 
If you have a boost leak performance shops do a smoke test - caus otherwise your just guessing 

Thanks it's because after he removed and reinstalled the piping it surged and hesitated under load.. Never did that before... I tightened the clamps and it improved it.. Some times it doesn't happen and sometimes it does... I think there is too many couplers which I think the leak is from... Good idea about the IC testing but i don't think it's that because it was fine before the major service... 

I ended up buying these Intercooler pipes...

Looks good quality and uses less coupling...
