i just got my car up and running again problem is boost gauge is only reading 3 to 4 lbs, hondata logger reads as low as 2 sometimes. someone i talked to said that they got low boost with the tial, we put in the valve seats no leaks whats up? will a boost controller be efficient when used w/ my wastegate? the spring is for 7 lbs i believe.. got it from importparts.com.

 

What pressure source do you have the side port connected to?

It's the .5 bar tial?

 

My TIAL did the same thing, turned out the bolts weren't down all the way. Since TIAL's use the Hex bolts, it was harder to tighten them enough. I used regular bolts and was able to get sufficient torque on them, boost is good now.

 

I have been getting low boost reading as well with my gauge. Sometimes only 2-3lbs at 5000rpm. I have my pressure source tapped into the BOV line going into the compressor. I have been told that if I tee it into my FPR line I will get more boost. Is that true?

BTW, so far I have my BOV, FMU, and boost guage tapped into the same source(my FPR line). Will that effect this assumption?

movethe BOV to a larger vacume line, like off the intake manifold... i had to do that for a couple problems when i first installed mine..

 

I have a .3bar spring and i usually only see .2, .25bar, until 4th gear it will reach .3.. possibly u have a .3bar spring

 

.3 bar =how many lbs di?

about 4 and a half pounds..

 

if i get a boost controller will it solve this nonsense? lookin at greddy profec B...also cuz i plan on boostin around 9 lbs.

 

Maybe you got a defective wastgate. Try a boost controller, it is worth a shot.

 

next week=greddy profec B at 9 lbs re-dyno.

 

that happened to me also, u just have to play with ur fpr

 

please explain to me what exactly to do with the fpr and what it does? I am having similar problems

 

You could have a defective boost gauge. I did, my gauge would read in vacuum with the car off, I adjusted my boost controller so that the gauge would read just above 5psi when I was at full boost. The car was really fast, but the vacuum reading always bothered me so I bought another gauge that read 0 with the car off, the first pull I did boost read 8 psi. So my first gauge was off by about 2 1/2 -2 3/4 psi. Luckily I didn't tyr to boost any higher with the original gauge.
