i´m still having issues
ok, i´m having this issues since i turboed my car, here´s my set up:

turbo t25
ecu jwt 3bar stock maf 370cc injectors
1st gen dsm bov
fmic, maf on blowtrhough mode
2.5 elbow on the donwpipe,(the one that goes welded on the J pipe) the rest i´ts of 2.5´ and 2.25 again to the end, no cat, no mufler (just for today)
turbosmart knockoff bost controller
autometer air fuel gauge

here´the facts, the car pulls great at low rpms but when i hit the gas pedal to the metal then just stop pushing i´m having this problem since the begginig, first time my timimng was on 10 degree, and when the car hits the 5000rpms it felts a notticiable loose of opower, like if was depressing the gas pedal, then i adjust the timing to 15 (i think so), and proved the car and the same thing pulls very hard on low rpms but at 5000 just stops pushing, now i didnt felt that loose of power so drasticly but still doesnt, making any power over 5000 rpms. with the gas pedal to the end.

i tought that i was having that problem because i was runing on the sotck muffler, i remove it completely and let te line free to check if that was the problem, today i went to the 1/8 mile track and the damm problem was the same i´m very dissapointed, a stock nx2000 beat me by a car

i know that i´m havving a boost leak because i tried to increase 2psi (i´m runing 7) and still the car was only making 7psi but 7psi are enough to beat a stock sr20de.

i wonder if my maf its getting maxed out and that could be the reason to dont make any power when the gas pedal its to the end.

tomorrow i´ll check the timing again with a timimng light, and the tps voltaje, and my intercooler piping to get that leak. and on monday i´ll do a compresion test.

i´m sick of that problem. i want my car runing hard on the entire rpms range

any advise for wath could be the problem

DSM BOV, KNOCK OFF BOOST CONTROLLER

REMOVE THOSE THINGS NOW.. the dsm bov is good but opens at idle hence running to rich ..check it for yourself..it also distorts maf signal get a greddy/hks/forge/apexi bov dont get anything stock cause it wont hold. i dont care what anyone says.

stop controlling your boost.. leave it off the stock wastegate if you wanna control it get a forge adjustable wastegate... if not leave it alone.
those two things alone will slow you down..

reason why u cant increase the boost is cause that controller is GAY. really gay like eats c0ck.


NOW DO THESE THINGS AN GET BACK AT US ...
boost leak... youll fukin know when you have booost leak.. youll thinnk the car is dying like @ low rpms.. you wont make it to 5k without freaking out
p.s. if you dont have a fuel pump... get one before doin all of this or motor will blow an youll never enjoy it ever.. youll probbably give up on it an get a lexus is250 an become big pimpin

baby steps bro.. first try the one thing that isnt gonna cost you money
remove the boost controller... if thats works out good.. you can leave the bov on for now.. also DSM guys use to crush theyre BOVS search it online ..
this again is one for 1st gen dsm bovs... 95-up an have plastic bovs that break under pressure if thats the one you have then youll need a bov really soon. like tmorrow... the 1st gens dont break only thediaphram is weak an opens under the littlest bit of vaccuum.

thank you for gettin back fast... i just want you to enjoy it cause bro everyday leavin work,school,gym,library w/e WILL BE FUN.

update
i advanced the timing a little and prove the car with the boost controler eliminated, it feels strong, the car was making only 5psi but it feels good, a mechanic was with me on the car and when wh prove it, he was cheking the tach to see were the car was loosing power while the speed was increasing, we reach 6500rpms in 1,2,3,4gears, and we didnt feel any loose of power

after that i changued the source from some vacums signals, i was using the canister vacum line to get signal to the waste gate, bov, boost gauge and boost controler, using some´s "T", now i just left the waste gate and bov conected to that line.

i remove the boost controler at all, now i´m geting the signal for the boost gauge from the fpr, i changued the clamps from the hose that conects the intanke manifold to the brake booster. that hose wasnt secure i could move it so easy with the old clamps.

it´s still pending to do a boost leak test to find out were that 2psi are scaping.

yesterday i was so dispointed but i know that i have to be pattient and do alot of research to find out what´s the reason to my problem, i dont want to give me up and litle buy litle solve my problems

i have done the boost leak test, i did it with an vacuum cleaner ridge like one of this picture
and i found 3 leaks i used a hose like this
to join some pipes and the tree pieces of hose that i used were porouse, just with the pressure from the vacuum cleaner the hoses looked like a shower, tomorrow i´ll change that damm hoses and redone the test

If your blow thru, the BOV won't have an effect on it...
