Excellent Product Delivered More Than Expected
Excellent product max pwr increase from 150.55 to 179.96 and torque from 138.52 to 188.93. I don't believe most of the marketing BS, so paid a little extra to get a dyno report. WOW! 3x better performance than what was promised. Nice. Buy this product. Excellent support but their software is needing an upgrade as it has bugs at the PC level. Needs better tech manual too.
A good but incomplete solution
The stage 2 Jet module I purchased for my 2008 Impala provided a subtle but discernible performance increase but because it does not affect transmission performance(shift points,firmness, etc.) it does not maximize performance from my cars' powertrain. I recommend this product because it strikes an acceptable balance between speed and driveability. Instructions were clear and installation easy.
