Update Looked inside the hole with a boroscope camera and it was full of dirt. Jacked up the car and underneath there is a hole near the side skirt that connects to that compartment (will attach a pic). Sprayed water up the hole and through the interior hole countless times until all the dirt came out. Car is fine now and doesnt pool water inside or leak anymore.

After heavy rain I noticed a lot of water soaked in the rear leftside passenger footwell. I pulled the rear interior out and got my partner to hose it down while I sat inside and checked for leaks, couldnt find one. I left the interior out and monitored it after a drive, water was there again, pooled on the body where the seat would sit and had ran down to the carpet yet again. Turns out the water is getting into the body and pooling up, coming out a hole in the side next to the rear door (I'll add a picture link). I had a rag in there, on taking it out a stream of water came out. Has anyone had this problem? Im guessing there is meant to be a drain hole in that compartment to let the water out, which has now blocked. What do others think? I hope this helps anyone having a similar issue and cant figure out where it is coming from.

Thank you Keith, appreciate the help.

Thanks for the info Keith, so even though they are the same pressure spring, it still wouldnt be wise cause they've been manufactured differently etc? Could a brand new oem replacement also in theory cause problems as my current spring couldve been worn out when I got the tune. My car had 120thousand on it when it was done.

After changing my turbo core the other day my wastegate has now sh*t itself. I was looking at buying a mamba wastegate kit with different springs. Now I know it has been asked a lot if you can put the 12psi spring in without a tune though as the kit comes with a 7psi spring I was thinking of installing that for now until I can get it tuned in the future. Would this be ok for boosting as it's the stock spring rate or would it be bad for it because the spring is new and firmer? The car has already been tuned to 304rwkw at 15psi on 98 as well.
