Hey I am having a problem with my wrx. I am having a really bad hesitation at 3800-5000 rpm. I was just forced to put in sti tgvl-ess housings due to a bad oem one. I have an uppipe, down pipe, cat back, and modded silencerl-ess intake. The car takes off at 5k rpm and seems to pull to redline now. Is this normal behavior, and do I just not have enought turbo to push throught them???

 

That sounds pretty odd.

Maybe your bad oem housing caused the ECU to pull back timming alot in that range.

I guess you could try pulling error codes then reseting the ecu by pulling the battery for like 5mins.

 

th battery was disconected for 24 hours or so while i did the work in my spare time. codes are for the tgvs only. circuit missing codes, will they screw up performance. i had a stuck open code for 4 months before i fixed it and it never hurt performance?

 

I gotcha, the fix should be fine. (2.2k resister i think)

Is your boost normal? I only ask becuase you may have an exhuast leak.

Hope you get it fixed after this i'm out of ideas

 

yeah boost comes on strong at 3k to 15 psi about but it just doesnt pull like it used to. the exhaust is fine it hasnt changes at all since the install.
