Trifecta Tune or PCM Tune?
I have just about everything ready for a tune, but debating on whom I should go for on a tune, got intake, header, exhaust, downpipe, 2.4 throttle body. That should be efficient enough for an XFE and daily driven IMO.
I hear good things from Vince of Trifecta tuning, understanding that his remapping of fuel is decent for a street tuned GM. We do have PCM of NC about 30 miles away that offers a full dyno tune for the 08+ cobalt PCM's.
Granted Trifecta will just give out basic numbers to recalibrate, turn off torque limiter, speed limiter, and a few other goodies. PCM will calibrate it correctly on a dynojet, cost difference between the two is only $100.
Which should I go for?
