Tunes at Altitude?

[sting me]

Hey guys. I'm about to move from TX to Colorado Springs which is about 6k feet above sea level. I took the Stinger out there a bit over a month ago, and it felt significantly slower than I'm used to, likely because of the altitude.

How do the various tuning solutions work at those heights? Will they still push the same power? Do they have anything to prevent causing damage to the engine components because of them working so hard at altitude?

Please share your thoughts!

Not a whole of discussion here on this topic but having the Stinger here in Denver for a year now, I can tell you that altitude and 91 octane are absolutely certain to slow anything down that isnt a pure electric car.

That said ive been running a JB4 for 6 months now and the results at the 1/4 mile and using a draggy have been my measuring stick for performance gains vs stock.
Starting off take a look at this videos where the Fast lane car test the car here in Colorado and gets a 5.4 sec 0-60.

That was pretty typicality of when i first had the car (AWD GT).
Bone stock at the 1/4 mile 5,800ft above sea level with DA's in the High 8,000 ft range the car with crank out 13.9 to 13.8.
When i got the draggy and JB4 it would do 13.44 in the same conditions picking up a few MPH up from 102/103 stock to 107mph on map 2. Its much faster now thanks mostly to the JB4 and map 2/3 and the BMS brake switch to launch harder 12.6/12.9 1/4 miles depending on the temps and air density.

I guess point is with or without tune the car still has to work a little harder up here to make the same PSI from the turbos.
I wouldn't say that its working substantially harder but it is working harder. No tune will fully overcome the loss's from being 5280 + feet in the air with less dense air. Gotta make more power just to be where stock cars would be at sea level. The JB4 works just fine at these heights nothing out of the ordinary.

JB4 is compatible at elevation but keep the mapping more conservative to offset the extra risk of turbo damage at higher impeller speeds required to compress that thin air!

And here I am running map 5

How's that working...what other mods?
