91 Octane

12/10

First Pull on 91 octane Integrated Engineering Stage 1 Tune

Changed DV to revision C with OEM spring, can feel car surging, losing boost.

I am wondering if my car is running good enough for a catted Downpipe. I would like to make sure that everything looks good before throwing on a Downpipe and a stage 2 OTS tune on.

Much better, Need to figure out open throttle compressor surge on load around 2K rpm.

This pull was on a freeway, while the other two were on a street. Car felt like it pulled not as hard. This one felt smooth and car drives good The V2 tune seemed to pull harder. Not sure if this is due to air temps
