L99 Magnuson Heartbeat S/C Kit Advice
So i'm working on tuning a '15 Camaro L99 A6 car with a Magnuson Heartbeat S/C kit. The supplied Maggie tune seems SUPER soft, hardly any timing with not even a hint of KR on any pull. Shift points are entirely stock at 5900, no changes to the trans section over stock at all.
I was able to determine that I could add about 5 degree timing safely, which pulled up the power nicely.
I want to move the shift points up a couple hundred RPM, but not sure if that's a good idea on the L99 with the DOD springs and already having 6psi of boost acting on the valve heads, worried about valve float/damage there.
Trans wise, any ideas on how much HP the A6 can handle? I would love to go in and set it up to have a little bite on the shifts like I do my N/A guys, but worried perhaps it's being pushed as-is. This kit is rated at 600 hp engine (obviously best case scenario at sea level), by the numbers it's making around 560-80ish at my location.
Seems to run pretty solid, but looking for any advice on boost tuning with the L99/A6 setup this car has.
Thanks!
