fitted my new -31 acuator today, played around abit and finally got it running nicely, took it for a test run and found that in forth it woulnt go past 4000rpm but it would in every other gear, i take it this is the boost limiter kicking in as my ecu is not chipped,

i will lower the boost slightly tomorro and see if it still happens, just wondering if im correct and if any1 else has had this

and please no replys saying take it to a garage, else i woulnt be asking this question
