After my recent rebuilt on my stock 93 FD, diffenetly i started to face some minor problems which is getting fixed slowly.

Lately after i started to have a hasitation on the rpm when accelerating and again i was abel to fix it and no more problem with the RPM.

Now the turbo are spooling and the car seemes to be prety good in power, but from 5k RPM to 7k RPM i feel its the same power (no dicrease or increase in power)
so i just wanted to make sure that the 2nd turbo are working or its normal or if there is a way to diagnose the 2nd turbo if its working or not!!!!

 

start off by installing a boost gauge. then go to the sticky with the FAQs and look for the link for turbo diagnosis/troubleshooting.

good luck.
