Haven’t done anything to my car in a while now. Did a pull today just to see if everything is working fine because it’s been a while since I’ve done one and it felt so slow. It made 346whp on dyno dynamics on e85 and it felt slower than when I was making 300. Did it again to see if the AFR or boost was off and it was only making 14 PSI in 1st gear. Didn’t do a boost leak test but don’t see or hear anything obvious. Any ideas?

 

Do a boost leak test first.

 

Drove to work today and back and it was boosting completely fine. Didn’t do anything to tge car since yesterday
