Idk if something is wrong or if everything is ok? Please give your opinion. I have two question. First my mods are as follows: intake, bov, uicp, licp, dp, tp,cbe and a Cobb Accessport. My question is I feel like its running worse than stock. Should I get a street tune? And second question is I'm dropped on tein s tech on oem shocks/struts. They have maybe 5k on the springs and 70k on oem struts. When I go over bumps I hear like a clunking sound. Not very loud but its noticeable. Any ideas? I have 17x9.5 wheels +20 offset

 

You definitely need a tune if you don't have one already. Any time you change anything it's a good idea to tune.

As for the clunking.. that could be anything. There is a huge thread on front end clunking noises somewhere around here, just search for it. Best bet is to first make sure everything is tight.

 

Yes, definitely get tuned, but more importantly datalog to see what the AFR, timing and knock sensor is doing.

LMK, if I can help more.

 

Do you have an aftermarket diverter valve or is it a vent to atmosphere bov? If you have a vent to atmosphere bov with the maf that alone may be your issue.

 

As mentioned, get a tune.

As far as the Tein S Techs, they are cheap, low end lowering springs. They only thing they are good for is lowering your car for looks. There are quite a few threads about the problems associated with those springs, specifically the fact that most people hit the bump stops on their suspension with them, thus blowing out struts and screwing up their suspension.

 

You forgot to ask if he checked for sugar in his gas tank.

 

That was my first thought!
