Pumaspeed X-37 Hybrid Turbo Thread

I'm running a Depo on a stock turbo and I've never seen below ambient. Except that one time I drove through Narnia.

The actual show that was on PBS ...way....way back was excellent. My dad read us those books and the Lord of the rings trilogy when I was young.

Just a heads up for anyone looking to upgrade to an X-37. I will be posting my X-37 for sale in the classifieds here in a few days once my new turbo comes in and I remove this one. I bought it brand new from Stratified a few weeks ago. It has 500 miles on it and will come with the big elbow, and Turbosmart 11# WGA.

This turbo worked great, but I need a larger turbo with more flow for my high elevation.

How much?

I may very well be interested in that! Why did you make the change/what did you go with?

I am making the switch because for me, at the elevation I live at, the X-37 doesn't flow enough air to overcome the thinner air to achieve the power that I desire. If I lived at a lower elevation, this would have been enough. Well, I say that, but we always want more power don't we? I am going with the Revo turbo.

I will probably be removing the turbo today and posting it up in the classifieds.

Gotcha, I haven't looked into the x37 too much because if I was going to spend the money I had intended to go with an x47r or the MRX, but at that price point now you've got me thinking. What were your numbers on that set up?

So is x-37 the least expensive way to go with maybe only a FMIC and downpipe needed along with the turbo (and wastegate and BOV)? Looking for current lower cost/lower power options, so who still does small/wide powerband turbo upgrades?

That's the ticket. Unless you find something used or someone changes there mind. I bought a brand new X47 R with Mountune catted downpipe and DV + and new NGK plugs for 2k shipped.

Has anyone switched from Tune+ to another tuner besides Ish? If so, what was your reasoning? I've had my X37 installed for over a year & a half, had the lifetime tuning from Adam before I bought the 37 so having him tune for 93 & e30 on X37 was a no-brainer. However, I'll frequently see negative corrections ranging from less than -1 to -2 across ign corr. cyl's 1-4 when going WOT & I've seen them get in to the -3 to -4's before. What's everyone else's experiences with negative corrections been? I'd love to stick with Tune+ but if he can't fix this problem I'm probably going to have to get tuned elsewhere. What do you guys think, any input/advice? I've been putting this off for a long time but I'm tired of babying my meanbean for the majority of the time I'm driving her bc being worried of the possibility of my engine going boom

What is your name and have you tried emailing me with said issue? If you have there is nothing in my inbox pending right now I haven't replied to. There might be if you sent it today as I have been assembling an engine for most of the day and haven't been back to my emails since this morning.


*EDIT, you just emailed me at 5:01p.m. today (33 minutes ago). I would appreciate it if you could send me a log of said issue so I can have a look at it. I'm not sure it was necessary to jump to switching tuners if you haven't given me a shot to address it yet. Tune hasn't been changed since September 2016. The tune hasn't changed so your corrections are a new issue, easily solvable with a little bit of dialogue.
