Did he tune your maf? You can set the power enrichment ratio as much as you want but without having the maf curve dialed in it isnt going to work out.

I agree...set the PE table...calibrate the PCM properly...then adjust the PE table while making dyno pulls or runs down the track to see what AFR the car likes the most.

Im assuming he did, he told me to replace the MAF and see how it runs. He said if it runs bad (very rich) he said thats a good thing. he said that means ur MAF was bad. But he said if it runs the same the MAF isnt the culprit. He said since the AFR is set at 10.1 but only producing a 13.xxAFR, if the MAF is bad, itll run extremely rich if i replace the MAF and it did end up being bad. make sense?
