Well, i've put off my custom tune for far too long. Today I finally got out to do it, and boy what a difference. Not so much in HP gain, but in how much smoother and better the car runs.
The car was tuned by Church Automotive Tuning in Redondo Beach CA, and they use a dyna pack dyno.
First, for all those curious, is a list of my mods for reference:
Tuning using Cobb AP, Cobb catted DP, Custom 3" Greddy TIC exhaust with no resonators or silencers, Corksport FMIC upgrade kit and top mount intake, CPE High pressure fuel pump, Denso Iridium colder plugs, Corksport Boost cut killer module, Buddy Club voltage stabilizer / grounding kit,
The tuning baseline was the current Cobb map I was running which was a V2 FMIC w/CAI 91 octane.
The red line in the dyno charts is the baseline dyno which was the above AP map. The torque curve really came on late, and the A/F was getting tossed around in the higher RPMS, and we saw some pretty gnarly knock. (the red line loops around because it was still data logging when throttle was lifted at the end of the run, so you can disregard the crazy looking loop the red line makes after the top end).
The green line is the NEW updated tune cold, and the orange is the new tune while warmed up.
as you can see, everything is MUCH smoother now, and the car gained a lot of torque, some HP and better AF ratios in the lower end, and the top end stays smooth with no knock now.
Ya know the Cobb AP maps are ok, but you should always get a custom tune, this is a pretty good example of that IMO
