APR still has the downpipe version of their IS38 tunes available but the stock DP one is not, at least when I got my IS38 installed back in Feb.Apr had one for a while for the GTI. They had a version for the stock downpipe and a stage 2 for an aftermarket downpipe. For whatever reason it’s not a thing anymore.
Yeah man that’s odd.APR still has the downpipe version of their IS38 tunes available but the stock DP one is not, at least when I got my IS38 installed back in Feb.
Its strange that they don't offer their Is20 Stage 2 tunes anymore but you can still get their IS38 ones.
I have the same turbo for about 20k miles. The last 6k on a flex fuel tune. I feel like I have more headroom for increasing boost, but rather keep it conservativeI'm running @projectTVMK7 's HPA IS38+ that he ran for 20,000 miles and now I've put another 8000 miles on it. Too early to tell about reliability but I have no issues to report of so far. If the + versions can provide the reliability that they state in their marketing then I'm happier doing that then potentially blowing up an IHI/OEM IS38 turbo that has to be uninstalled, shipped, re-installed. Especially true if you're like me and need to have a shop do the install.
