I need more air...........

Subject: I need more air...........
by Weavsvet on 2010/6/24 19:21:28

At least my tuner says I do. I finally got a WOT data log to him. I'm runninga OE intake with a cut lid and a K&N. Here's what he had to say........

Two things I noticed are that your airflow reading is not very high considering your mods. I would think it should be a good bit over 300 gm/s, but yours is just barely breaking that. The other thing is that your MAP reading is not staying close to 100 KPa at WOT, which usually indicates an airflow restriction or valve float could be related to the low airflow reading).I would check out that in the meantime.

As far as the valve float I upgraded the springs on the AFR's to the next size springs(8019 I believe). I knew I was close to their standard springs with the lift I have plus the 1.6 rockers. Thoughts?
