Very brief....while at work today I had a chance to use the DECS program from the Driveability Guys. I purchased it from AESwave. This program is great! VE Calculator, Catalyst Efficiency, Combustion Efficiency, Conversion Calculators, etc. I am still in the process of learning and understanding the software. It has helped guide me in the correct direction and is yet another tool for our busy days. It has saved me time. Hope this is something that can help others!!! MAF (skewed) and Intake Boot (lean) for the win. Note: The before specs were 4% efficiency.

Samuel, thanks for the "end user critique". DECS appears to help techs save time, similar to the comparison of a Relative Compression test being a time-saver to the "old days" method of pulling spark plugs. Also, I like hearing of techs happy with their tool investments instead of hearing from those who manufacture or sell the tools. To me that has more value.
