Hi,
I have a 2JZ-GTE swapped Lexus GS300 and i cant seem to get it to boost propperly.
i have done following mods:
- 2½" Exhaust freeflow all the way.
- Walbro 255LPH.
- FCD.
- Front Mounted Intercooler.
- AEM Wideband.
- AEM Boostgauge and Electronic Boost Controller.
- Denso IK22 Plugs.
I can get it to peak 18psi at arround 4-5k, but then it drops to arround 9-11psi. Then at 6.5k it raises abit but only 1-2psi.
I have tried both Sequential and TTC Mode and it is the same result.
Could it be the Electronic boost controller or what could be the problem?
I have tried both Manual end Electronic Boost Controller with same result.
Here is a video where you can see the problem. The car is in TTC Mode in the vid.
