low boost numbers...

[black cloud mafia]

hi everyone im new to the site and have a question. i just put a edge evo. 2 tuner in my truck and while i drive down the road it reads 0-3 psi for boost, and under a load it will go up to 9 psi. and there is a huge cloud of black smoke(looks cool). is it my tuner or the truck computer? or is my turbo toast? or somethin?

an help would be great cause my local shop charges an arm and a leg to look at stuff so i do all my own work if i can
thanks guys

I'd start by checking all the boots to make sure they are tight- 2 at the intercooler, 4 on the spyder pipe (2 on the CAC tubes, 2 on the plenums). Also check for up-pipe leaks (the pipes that connect the exhaust manifolds to the turbo).

What does it do in the stock program?

In stock mode does it feel like its lacking in power?

[black cloud mafia]

no in stock mode it feels normal. do you think the boost senser might be toast?

i also seen on here where some guys were talking about there intercooler were getting clogged

Take a quick look inside your intake and make sure your turbo impeller does NOT look like the first pic. The second pic is good, first pic bad.

you mean it only hits 9# max when you really put the pedal down? mine sits around 3-5 when cruising around town/hwy depending on speed. that's just cruising though, no acceleration really. is that not normal?

check your up pipes as well...

what are your EGT's numbers?
