Argh... Opera Mobile fail after trying to post the last message.
Please excuse my ignorance. Does anyone know if the IAT is integrated to the MAF? Perhaps IAT is getting heat soaked causing inflated readings by the ECU. Has anyone attempted to use an external IAT and relocate it elsewhere?
If MAF was an issue then I would end up with rough idle and maybe get a CEL, but there isn't any and the engine idles smooth. I do notice performance is worse off the line on a warm day after being stuck at the light for awhile, which is why I lag getting through intersections and making turns. So maybe IAT is reading higher than normal, and the ECU is responding to the inaccurate readings.
[EDIT] Eh, I feel stupid.
IAT location?
Intake air temp data (Stillen Gen 3, need stock)
With the turbo kit, my MAF sensors will be relocated anyhow. I'm going to ask Sam@GTM about it... For N/A owners... perhaps it's something to consider. I'd like to see if CAI owners can chime in.
