They've tuned enough vehicles to have a MAF scaling that works, and they typically tune OLF table on the richer side, so even if the scaling is off a bit, it's not going to lean out too much under high RPM/load.Thats unfortunate. What are some indicators i can look for in my logs to make sure im running safe with the CAI? Also i noticed most professional etuners dont require a wideband o2 sensor when etuning a car, how can they do it?
Also is it possible to use someone elses maf scale that has a similar intake on the same car?
If you can find MAF scaling from someone else, you could use that and be better off than OE scaling (assuming it was scaled properly). However, you need to know/trust the source, as it has a direct impact on your fueling.
There are variances that will come into play. You won't have a perfect scaling using one off the Internet, but you can get pretty close. Personally, I would tell you to spend the $150 or so and buy an AEM UEGO and just do it properly (that's a handful, or less, of nights out with your buddies you have to pass on). You'll have a better running car, and the gauge can help notify you of issues that could cause catastrophic engine failure if not detected.
