2G cant go past 4.5k rpm

[Codyvieth]

MY 95 eagle talon tsi doesnt allow me to go past 4.5k. it has a 16g turbo still running stock boost and 190 fuel pump and a recirculating hks BOV and intake with a cone air filter and intercooler. I have no fpr but from what ive read online it shouldn't be a huge deal. my air fuel gauge reads that im running super rich when i hit boost so i was thinking it could be a boost leak but i don't really have a good way to check that right now. my boost gauge will read up to like 8 or 9 psi. the only other thing i was thinking could be wrong is the maf. when i hit like 4.5 its not at all like hitting a brick wall like ive heard other people Describe with the similar problem. it just goes to 4.5 and just doesn't feel like going any higher i guess . also there is no CEL on. also it idles a lil rough and when i shift it seems to almost stall and then the rpm goes back up[DOUBLEPOST=1407719826][/DOUBLEPOST]I checked to make sure all my piping had good conections but I couldn't find any thing bad I also looked at the fins on my turbo and they seemed fine[DOUBLEPOST=1407732207][/DOUBLEPOST]also forgot to say that it doesn't make any weird noises and it feels pretty slow when i try to accelerate.

i think theres a leak at the blow off valve im going to buy a new gasket for it this weekend. probably gonna gut the cat also. i just got distracted fixing this because i started having other problems i had to fix

Kinda forgot to post about fixing my car but it's better to be late then never. Any way the problem was 2 massive boost leaks. The o ring is also bad on my bov I already ordered the part for that though.

Thanks for replying back! Glad you got it fixed! Bet it feels great to finally figure it out.

i was having this same problem and i had to get the car tuned but i was on a slightly different setup i was on 16g 560s stock boost walbro 190 and a fmic with 2.5 pipes and it ran like shit i put the tuner in and it started to run way way better i know you already found your problem but just in case someone else is reading through this that is having a similar problem

Yeah my 16g was shit so I got a used t25 that was in good condition for 40 bucks. Probably gonna keep buying shit for a 16g set up during winter so I can run a e85 tune this spring
