Cheap 10rwhp/14rwtq Dyno Proven
So today I went out for a couple of dyno pulls and on the first run the operator noticed the average AFR with the stock tune was 13.8 and we were like wtf?!
That run logged 226hp/229tq. He asked how long its been since I cleaned the MAF and I haven't since I've owned the truck. I pulled the MAF and we cleaned it and on the second run still with the stock tune it made 236hp/243tq.
Pretty cheap little power adder I thought lol.

Yeah this guy was saying its a big problem especially with wet CAI setups.
I've kicked around the idea of running a SD Tune, but don't want to retune everytime the weather changes. I've definitely noticed better response in SD though.
I also found out that my "tune" needs work...picked up a whopping 1rwhp lol.

Actually I like to see the afr around 12.6 to 12.7 around peak torque and lean it out on the top side, usually to about 13.1 or 13.2. Some like richer some like a little leaner. Mine likes a little leaner on the top side.
Another thing to think about with the dirty maf is that the spark tables are based on grams/cyl airflow so if you are reading lower airflow you may be in a higher timing area of the map then where it was tuned to run at wot, this may get you some knock retard.
