I'm looking for some input/advice.
As some may recall I recently traded in my 2LS for a 2015 Regal 2.0T . It's actually really peppy (despite the snarky disposition of some members here).
Motortrend had it in the low 6 seconds 0-60 which impressed me enough on paper to try and end up buying. I never go to the track so the mushier handling is just fine, and even then it still handles really well. I've been tossing it around a bit in the 2300 miles I've put on it thus far.
On to the point of the thread - I suspected I would end up tuning the car, as the
tunes available from Trifecta boast some big increases. Unfortunately in doing my homework I came across a thread on the
Cadillac ATS forum regarding a couple very serious problems with the LTG 2.0T (same engine as in the Regal and optional for the Malibu). One is for (supposedly) faulty pistons, the other a
manufacturing defect (bearing) on a very small percentage of engines, causing them to fail within the first few thousand miles.
I'm trying to make sense of these issues. The ATS forum is flooded with piston failures, and yet the malibu and buick forums are quiet (no widespread reported issues). The ATS owners even note this in their own thread (why does it appear they are the only ones using this engine experiencing the issue?).
To tune or not to tune, that is now the question. I'd hate to lose out on a relatively significant bump in performance (the transmission tune would be very welcome, as would better throttle response, in addition to the increased power). But I don't want to hasten the death of my engine either.
Anyone with more knowledge on this subject? I know we have some serious car guys that are members here...
This might be of greater concern to the Camaro community if they end up putting the 2.0T engine in the Gen6.
