Our calibration has three stages available to accommodate any modification setup.
Stage 1 Calibrations are designed for stock or lightly modified setups. We increase the boost pressure slightly, and make small adjustments to driveability. Perfect for those wanting a bit more power out of their daily driver.
Stage 2 Calibrations are designed for lightly or heavily modified setups with the original turbocharger. We make further increases to boost pressure and ignition timing, as well as small adjustments to driveability. Perfect for those wanting substanitally more power out of their daily driver.
Stage 3 Calibrations are designed for vehicles with our upgraded hybrid turbochargers and supporting modifications. We increase the boost pressure substantially, and make major adjustments to driveability to accomodate for the larger turbocharger. These changes yield an immense power increase.

This is EXACTLY what I was looking for. This tune offers so much bang for the buck, my only regret is that I didn't get it sooner. Runs like stock when I want it to and then transforms into a torque monster when I put my foot down. Thanks SXTH, you guys are amazing!
Okay. I had the sxth advanced and stage 1 high torque tune before the ek1pro came put. Ek1pro came out so I got that after going fbo (dp, intake, inlet, fmic and boost pipes, occ, rmm)along with a stage 1 revision and stage 2 tune. Long story short, after good customer service and 4 revisions to my stage 2 tune. I was finding my N was hitting peak boost at barely 35% throttle... Nathan said this was due to the aggressive throttle on the N but I find that hard to believe since you can tune the throttle and much more on the unlocked ecu. It's bad when you don't feel a difference going from 40% throttle to 100% wot. Sold my ecu and ek1pro and dont plan on ever going with a sxth tune again. They only go high torque tunes. Blame the hpfp etc etc. I wish this platform had a more communicative tuning company that took ownership.

Stage 3, Turbo Upgrade Tune = insane. Super satisfied with my experience. Customer service has been great and responds in a timely fashion regarding my tune questions. I also ordered the 4 revisions and highly recommend for any purchaser so you can dial-in your tune. The EK1 capabilities are awesome; writing to the ECU is super quick and recording data logs is simple. Shoutout to Nathan A. @ Sxth for going above and beyond to help his customers, for finding the time and providing insight and helpful information when other companies didn't even bother.
Stage 1 High Torque. With other mods (intake, downpipe, FMIC, exhaust, etc.) this spare ECU tune is a MUST to get. Also, observed an improved 2+ MPG. I have had another tune before this, but this is on a different level. Get this one!
Amazing. The car runs like stock when I want it to and absolutely wakes up when I put the pedal down. Fantastic tune
The stage 1 high torque tune has completely transformed the car. Power delivery is super smooth and the torque is insane. If you have a bolted N this is a MUST. Sxth Element knocked it out of the park and on top of that I feel confident being backed by such excellent customer service.
