Thats exactly what I'm thinkin. I will install the maf and headers. Because of the lean tune I paid for I hope to convince the tuners to give me the additional tuning free or at least with a good discount.ponyboy19 said:your definetly to lean.. should be around 11-11.5:1. You really need to see how much boost your pushing. Also remember once you change your mass air, your tune that you just got is worthless. the MAF parameters will be different and will require a new tune. but it looks like the tune you have isn't too great anyways. I'm not a fan of C&L meters especially with blowers so i think your on the right track with the the new meter and headers but i would retune it and get the a/f down to around 11-11.5 and total timing around 20-22 degrees and see how it responds. you may also want to look into an ignition box at some point.
