The TB's on the 3.7 stay open at 100% I believe. The VVEL actuator basically allows the valves to function like a TB by increasing/decreasing lift and duration, only using the valves and the eccentric cams rather than the actual TB's. Anyhow, until we can get control over VVEL, LTH's are a no no with SC setups I guess. Hence why I said LTH would most likely not be an issue with HR's since cam timing can be altered using Uprev, unlike the VHR. I guess we'll just have to wait and see till more testing is done. Thing is, even if Uprev does allow control over VVEL timing, I personally don't trust any Pro Tuner to be able to properly adjust it. good thing I have an HR G35 I guess lol.
