91 turbo wont rev pass 5k rpm
 

Hi guys,

After a year running my car with a Speeduino PnP I decided to turbo it and now the car wont rev further than 5k when it gets temperature. I was almost sure that my issue was fuel pump related because something like that happened few years ago but I instaleed a new AEM intank 340 LPH fuelpump and the problem persists.

Any ideas?

Thanks in advance

Edit: I have 420cc inyectors and oem fuel rail and regulator, no overboost protection set

Edit 2: problem solved, it was the launch control ON shame on me
