Boost Leak

DocSolis · 07-05-2013, 12:16 AM

Wondering if anybody had boost leak code right after installing catless dps and fmic. I just had both installed and there was no boost in the car i checked with the cobb ap and got the p30ff code and engine malfunction when going wot. I was running stage one agg. on the cobb prior to installing the fmic and dps and never had any issue with boost, only issue was misfire which was taken care of with new spark plugs and coils. From research it seems more than likely it something that's loose or wasn't tightened properly on FMIC. So trying to get input and also if anybody had the same exact issue. I'm still kinda a newbie at this tuning stuff but hopefully this isn't a issue that gonna take a while and whole lot of cash to figure out and fix.

Yeah, one of the FMIC couplers is probably loose. Check those.

+2 prob the issue. Tough to get them properly aligned during install. If that doesn't fix it, you will want to get/do boost leak test. Could have faulty intercooler.

I had a boost leak after fmic install. I made sure all the clamps were nice and tight and tried to arrange the silicone couplers in the best arrangement to get a nice seal. After that I kept getting the under boost code and went back under the hood to find that one of the clamps was loose. The best thing to do is run the car after the initial install and then go back and tighten everything when the car is warm.

Thanks guys, I'm gonna check out the fmic connections later today would've done it yesterday but got the car back from the shop late and it was 4th of July I had the itch to blow shit up since I got out of the military so yesterday was fun popping some fireworks while somewhat intoxicated. Disappointed in the indy shop since the owner is great with customer service and he is very knowledgeable in tuning but I guess his mechanics aren't.
