Dynoed the cobalt today N/A

Did some pulls before the tune to see where I stand mods include

Cai, header/dp, exhaust, flywheel, velocity stack (no filter), tb

Best pull was 178whp 175lb with NO TUNE !!

I'm guessing that was just a part throttle roll into the correct speed since its a short rpm range

Looks like it still has that nasty stock torque dip at 4,800 RPM but I can't see the RPMs at the bottom of the sheet to tell you for sure.

Almost looks like they let off a bit and then hit it, but the consistency for the runs says its in the tune which is a bummer

I would just find a SC or something instead of sinking more money into this. Gonna cost way too much to actually make power.

Also the graph looks weird cause some dyno's have trouble picking up a proper tach signal from our cars. Last dyno day I went to the only cars having issues getting readings were Cobalts.

With all the typical bolt-ons, no tune was 148whp and tuned was 163whp both with an unlocked torque converter. My tune was aggressive though and I had access to better fuel. Now I'm 4000ft altitude and with half ethanol I barely eke out 165hp with the converter locked. 155hp unlocked. It sucks.
