Late boost problems

[s13_brad1993]

Hi all got my 14 few months back just been slowly sorting bits out and now wanna get on to sorting the late boost issue out , I only boost at 4K sr20 no boost leaks turbo seems fine t28r as far as I'm aware just wondering if there is anything I'm missing :/ I'd like to get it down in the rev range to kick in sooner
Cheers

how do you know if you have no boost leaks, has it been smoke tested?

that turbo should be on song by around 3k at very most

Not been smoke tested but no obvious boost leaks

no, you have to smoke test. a look over won't reveal leaks, trust me i know first hand

[s13_brad1993]

Fair enough mate I'll look into getting that done then could there be any other things to look for

I'm 99% sure its a boost leak, it comes on boost so late as more of the boost is lost, the turbo works even harder to produce the desired boost level which is generally further up the rev range, by that point the turbo is knocking its stuffing out to produce the boost you want

Fair enough will look into smoke testing it ASAP then , it has been like it since I got it
