Default Anyone have a boost curve for a dom 1.5xtr?

I am about to dive in and purchase a stock location turbo. After seeing Topspeed's thread on testing the don 1.5xtr I am just about convinced. My tuner would like to see a boost curve of that turbo on an ej257 but I have not been able to locate one. All I see is hp and tq. Little help?

Cool. I just found one in a thread on here titled "2011 Sti, Dom 1.5xtr,8cm, 92/e85 (turbo sent back to Blouch)" for anyone else interested. Did you opt for the 10cm hotside by any chance? I appreciate your reply btw.

I'm considering this turbo myself, there is a thread here in the power proven forum. Was really impressed with the 10cm, spool up wasn't much worse than the 8cm and it had a little more up top.

So the results are in the car made 350hp on pump gas and 400hp on E85 with the Dom 1.5XTR and supporting mods, ill post dyno sheet soon in the proven power threads but spool up was real fast and held consistent power all the way to red line

Good power! I'm sure you are pleased. 92 or 93 octane. Looking forward to see your Dyno chart. Does it feel "laggy" at all?

Thanks for your input. I just received my Dom 1.5xtr. I went with the 10cm hotside. Hopefully I didn't make a mistake going for the big one. Did you have to upgrade to a big Maf housing? I'm just about ready to install an get it tuned. Can't wait.
