So I decided to do a data log and I noticed I'm only reaching about 11 psi when it was originally tuned for 15. I think it has bin like this for a while as it feels the same speed since I started driving it this year. I haven't changed anything in the setup expect the tranny. I have emailed the guy who tuned it and haven't gotten a response back yet. I am using aem ems with aem tru boost gauge. Any ideas why

 

Did you check for a boost leak?

 

What he said...boost leak.

 

Check all the fittings on the wastegate

 

11psi wg spring and your boost controller came unhooked or a bad wire? I had that happen to me.

 

Did you boost gauge always only show your hitting 11psi?

 

Im a noob when it comes to fixing turbo setups. To check for boost leaks do i make sure all the intercooler piping couplers are tight? I will check the waste gate and mac boost solliend to see if any lines came off. I dont even remember if it always said 11 on my boost gauge as i rarely look at it.

 

All my lines are good. seems like my tru boost is not switching to high boost mode as im getting the same amount of boost in each setting. i did have my tune modified over email im gonna put my original tune back on and see
