I've got a Reaper truck in for some diagnostics and tuning. It's the supercharged 5.3 package and is, in my opinion, embarrassingly slow. I think it is mostly tune related as the tune has 0 changes to virtual torque and virtual ve. It's MAF only with a stock MAF curve and timing.
In order to "do it right," what's the recommended parts needed to report boost and the correct pressure ratio? I believe i just need a DSX baro breakout harness and a C6 ZR1 3 bar MAP... Is that correct? Anything else necessary?
Next question, is it worth it? Or should i just correct fueling as is, tune the VVE and virtual torque as it sits, and send it?
Thanks
