well im k03 will boost to about 18 or so and by redline it will be back down to 8.....that normal?

 

read up. k03 chipped. should boost from 2k to 4k ar 18-21 psi. 4k-5.5k it should be around 15-10 psi gradually dropping

 

I dunno what to tell you, not every car is the same and sometimes its
the software. At least in my case, i dont hold more then 10, but maybe
you should just look into new turbo ko4 etc and if you dont get the psi
you want then you go from their. Just depending on where you plan on
going next. like i said, i peak at 16, and hold 10, software or not? But then
again, no chip should max at 16 thats just attrocious.

 

well if i get the k04 will it hold the boost over 15, and why does some of these guys with my same setup hold boost and i dont?

 

I would copmplain if its allways been like this. But my turbo used to boost to 21 and hold at 18 easy. and it hele earlier at 18 WITH a boost leak. not it isnt and its gradually getting worse

and you could have a boost leak. if you hold at 10 between 3 and 4k, then you defanitly have a crapping turbo, a leak, or a issue somwehere. that would be low cor any chipped car. if its not chipped, then that is normal boost

 

in third gear i hold above 15psi until about 5k and then it goes down....
