Boost/power problems

[Prodigyman]

Since I installed my new FP BT28 (ported too) I have a lot of power loss. Basically right now it doesn’t have all the power and barley reaches full boost @ 6K RPM and it’s only like 10 PSI. I know since I installed those solid SMIC pipes. I checked and rechecked the piping and everything but it’s all right. Since I didn’t build any sort of boost leak tester I just took stock Upper pipes and putted them back on. Lower one is still S bend from turbo to stock SMIC. Now car drives little better still eats 80 miles for 20 bux of gas but drives little faster but still slow.

I have

Injen Intake and K&N filter
FB Big T28 ported
2.5” hybrid Connection from SBR o2 housing
2.5” DP
3” HIGH flow CAT
3” cat back
With 4” magna flow muffler
Greedy Profec B II EBC
Turbo and other gauges
ATC 2100
Brand new o2 and secondary o2 sensors
Light pulley
Type S BOV
STOCK boost for now aka ~12PSI
And more stuff I cant remember/not performance important


Anywayz what I am wondering when I get my piping kit from English racing for my 31” FMIC (kit comes with very nice pipes J clamps and very solid kit overall) could there be a possibility of any other boost leak? Because what I have right now from intake to intake manifold I am 95% sure no boost leaks there.

PS: From adjusting my Greedy Type S too many times my main threading is gone and stuck in one setting and the nut on it cant be screwed hard (just fed up the BOV few days ago) would this have any affect on boost leak? BOV still goes off and everything is fine.. Just cant adjusts it anymore and threading is gone….

Also when its hot or when A/C is on car has NOOO power at all, about 100HP or even less its just so wired also. Hot day like 35+C car doesn’t drive period, I might as well be pushing it or something… (water temp is fine though)

Any help or suggestion would be really appreciated

build a boost leak tester (www.vfaq.com) and spot the leak. It sounds like that may be your problem. The decrease in gas mileage might be due to you car running extremely rich and all that gas is being dumped out the exhaust.
