could also be colder dense air in the morning vs humid warm in in the afternoon
considering PA had about a 20 degree shift in temps between 8AM to noon today

If you want some audio of an CS400 paired with a JDL uqfp and Perrin 2.5 resonated system.

Is it possible to get the CS400 ceramic coated? I'm probably going to pull the trigger at at the end of the year.

It is if you get it through CSG.

That was the plan! Just didn't see the option on their site.

So got the CS/400 installed and tuned on 91 pump gas. Definitely a better daily driver and power starts building much earlier.

Maybe I was expecting too much from what I read from other CS/400 owners on the forums but 2000-3000RPM seems unchanged in a way. I had the feeling that it would have much improved low end torque, I guess I assumed wrong?

Maybe it should have more torque in that range and it's just the gas I'm using? I'm just wondering if there is anything I can do to improve that RPM range without needing to go with a supercharger.

ACE Type-A 350 and CS400 smooth out the powerband. Uncertain which tuner supported you to help validate the tuning parameters, but our tuning requirements make the power output and delivery quite smooth so you don't feel a "kick" in power, but rather just note the speedometer numbers rise a little quicker. What you may be feeling is a smoother power delivery. To be fair, this engine is a 2.0L naturally aspirated setup so you can't expect to feel forced induction levels of power delivery.

Zach from Delicious Tuning helped out. I guess I just had unrealistic expectations. Other than that the header was worth it.

That's good stuff. Short stroke vs. long stroke motors build torque differently. It's a high revving engine so it's not always recommended to load the engine around 2-3000 RPM.

If you want more power between 2-3k you should get a V8.

A 4-cylinder should be driven gently at that low of RPM. Trying to accelerate briskly in that RPM range puts a lot of heat into the bearings on a small engine. It's a great way to throw a rod if you're boosted.
