new ported heads, long tubes

so i installed new ported heads, timing chain kit, hdx secondary chains, mmr seconday, tss billet gears long tubes, and pro chamber.. car just dont sound as strong from what i can hear.. no tapping noise, no ticking etc. but it sounds like car is more relaxed and putty. but driving it seems to have power.. where to start to eliminate problems?

I guess i'm not following what you are chasing. You say the car sounds more relaxed but runs harder? That makes sense if I think about it in my head as the engine is breathing much easier with all the added airflow. I havent experienced ported heads on these cars myself but it doesn't sound like you are having any negative effects unless is is being a huge dog down low or something.

As for the tune, I would definitely have it rechecked just to make sure. You changed the airflow efficiency of the heads and fueling will need to be corrected for that.

Get rid of that pro chamber if you want it louder. I had one briefly and ripped it out and went back to an X pipe. Sounds like you have a smooth running engine is all.

will have it on dyno the 23rd im wanting to do a 93 tune and e85 only bummer is i added long tubes along with the ported heads. wanted to get some proof of there ability of power but besides power there help of lowering boost restrictions to help keep her alive longer
