Trifecta Budget after GMPP (lost GMPP?)
Bought my 2009 sky redline last year. First thing I did was GMPP tune at dealer for $$$. Then in order... solo hfc cat, probeam, back bone, and a few days ago trifecta budget tune to be activated by traction control. Car is amazing , but I have some observations/ opinions
What I have realized is that when trifecta is NOT active, I do not have the gmpp... it’s back to stock.
The other thing I’ve realized is that trifecta budget has enough power to spin the tires and get you sideways a little too easy even with competitive mode assisting.
This said I would recommend anyone get the cruise control activation. That was you can have tune performance regardless of traction control setting, but can be turned off for cruising or for other drivers.
The tune is amazing, smooth, and a noticeable improvement over gmpp. I highly recommend it.
Only disappointment was not realizing I would be losing GMPP. Stock boost back down to 16 from 19. Trifecta peaks at 27.
Great news is that since I asked first day after install it looks like WOT is allowing me to switch to the cruise control activating allowing full boost with full traction for full safety.
Any feedbacks or corrections welcomed. Just sharing my experience with future buyers.
