So what your telling me is the LQ4 reads the same freq as the L67 Maf given the same exact setups? WHen I say Higher ceilings I invision going to the Lq much like when I went from a stock L36 tb to a l67 the maf freq droped about 300 Hz. (the L36 gets like .021 grams of air a sec and the GTP .024 GPS). I dont have any experiance with Lq4's But I could see the fact that its in a much larger part of the intake the Freq would drop even further and give you a much Higher ceiling. So if you were hitting 11,500 on a l67 you might be around 10,000 on the lq4. Am i not correct?
