Hi guys, im running a GTX4294R on my car. I was wondering would i see full wastegate spring boost presure in 2nd gear? Or would i need more load on the engine to see this ie be in 3rd gear. Watching videos of setups and it seems people are making decent boost of the line but then could this be down to the way the cars have been mapped? All advice is appreciated!

This is true but the cars made more power with this exhaust system on the old set up. The system has been on the car for 1200 miles. I have spoken to many people they have stated that this should be okay even to see 600 bhp. I will take the system off and leave just the down pipe on to see if it makes a difference. But I don't think it will.

I didn't check the boost leaks the mapper said he tested for them. He found a leak on the turbo elbow on the aluminum welds and BOV. This was all corrected ground back and re welded, BOV was removed and replaced with a straight pipe but still don't boost any higher. However it made the same sort of boost if not more when it was leaking at these areas and with the old waste gate. I double checked all the clamps/jubilees on the hoses from the turbo to intake.

mines is not miss firing just don't boost any more, However I did have a miss firing issue on my first start up and replaced all the things you stated. My issues was a sensor ground the mapper found and issue was resolved. He said it was a pin the loom car side pushed back.

Hi guy's, Just wondering if someone has come across this issue i am facing with my supra. The cars a 6 speed single running a garret gtx42. Issue i am facing is the cars not boosting over 12 psi? The car has been with the mapper who started to map it on the dyno. The car was making 525 bhp @ 16psi. He stated he couldn't get it to boost any higher than 16 psi. The mapper tried to re plumb the waste gate to run infinity boost but the mapper says its not boosting any further. He told me i had a faulty waste gate and stated it needs to be changed. So i had a new precision turbo waste gate fitted running a 16 psi spring combo. The mapper states the cars now pulling 400 bhp @ 12psi and still won't over boost if re plumbed. There is a Titan Motorsports MAC boost solenoid plumbed. But I've been told this has been by passed and makes no difference to trying to get the car to boost any further. I have checked all boost leaks and there is none on the pipe work from the turbo to inlet. The turbo i know is in perfectly working order. The ecu used is a AEM Infinity. I have not seen any ECU settings. Any ideas as i am running out of options? I can't also under stand how its now running less psi with a new waste gate and spring. Any help or advice is appreciated.

I'm still after one of these? if any one has one please pm me along with a price.
