I just purchased HPT primarily for a couple other vehicles, but I'm thinking I may want to use it on my LML as well.
Currently I have a tune from a vendor, using ezlync, that has recently had some poor reviews on the quality of their tunes. These are the issues I am having:
1. At idle it goes back and forth between a deep rumble and a high pitch whistle, like every 2 or 3 seconds. I prefer the sound of the rumble, but want whatever is best for the vehicle in terms of reliability and performance.
2. It flutters when you let off the accelerator pedal, and I have heard that is bad, so I would like to fix that.
What sort of things can I look for in the tune to edit in HPT to resolve these issues?
Thanks!
