[QUOTE="Shaun@AED, post: 11421387, member: 32381"] Valvesprings shouldn't be a big deal. Huge cams presents an issue with Piston to Valve and valve on valve contact during the overlap phase. Care must be taken. Ideally piston to valve is measured, then phase limiters built to ensure the ECU can not command TiVCT settings that will result in P2V issues (factory limit is 50 degrees due to P2V). Then valve to valve contact should be measured and Overlap limits set in the Tune. (factory tune limits overlap in TiVCT tables) Very complicated and most will not go that far, so the aftermarket makes phase limiters (limits to 20 degrees vs 50) and lockouts to completely eliminate TiVCT. I'd like to see mild cams that allow full TiVCT movement and limiters in 5 degree increments (45, 40, 35, 30, etc). There's no need to limit small profiless to 20 degrees, and larger profiles can be set on different 'Park' angles to allow greater than 20 degrees movment without issues as well. [/QUOTE]
