GIAC Chip
Just installed the 93 oct. GIAC chip in my 2002 s4 today. The chip was one i bought here from the forums.. it was a full ecu already chipped. The box is an m box.. and my stock box is a t box. I looked through the forums and they said they were interchangeable.. but i'm experiencing some problems. The car starts and idles fine.. but when i rev.. it sputters as it revs up and than falls all the way back past 1000rpm and than stalls. Any ideas what's happening? I thought it might be because i was running 89 oct. So i threw the original ecu in and ran it until it said there was 0 miles left and than i put 93 in.. thought it was running better.. the rev up didn't sputter as much but it still stalled on the way down. Any suggestions or ideas would help. Thanks.

Found Boost leak
Hey guys, found a boost leak after testing it yesterday, here's the picture of what hose it is, highlighted in red.
Also here is the hole in the hose itself
When i found the hole.. i took the hose off, and since it connects to the n75 valve.. i removed it from there, but when i did the n75 valve pretty much feel off of the hose, spring and all, like it was barely attached. So i ordered one from audis4parts, and am now waiting for it to come in. Do you guys think that small of a leak, combined with possibly faulty n75 valve, would be enough to throw the p0102 code and make the car stall upon starting? Also any suggestions on vacuum hose sizes for replacement, auto zone has a kit that has 10 ft. of 4 mm., 5 ft. of 6 mm. and 2 ft. of 10 mm. hoses. Here's the Info
Think that would work? If i'm buying the kit i guess i'll just replace all my hoses. Any more input from you guys would be great. Helped a lot so far.. have a feeling i'm getting pretty close to having a working, chipped, S4 pretty soon.
