Wondering what kind of turbo lag and drivability I would be looking at with 5-6k elevation in most places.

Thanks for any insight!

You'll get more lag and make less power, but NA cars are even worse off

I'm at 6200 ft elevation. Got my Stage 3 tuned by Avalon in Denver. It made a WORLD of difference.

I didn't know Avalon did custom tuning on the B5, but I guess I should have guessed as much. Brian mentioned he was going to start offering it, but I never heard anything more, and that was several months ago. What SW were you running prior to the custom tune, how much of a difference did it make number wise, etc? Thanks man!

Wait, are you Chuck?

Yeah, I was Brian@Avalon's guinee pig in terms of being the 1st Stage 3 B5 S4 that they custom tuned. Originally, I had OTS GIAC software. It was decent, but definitely no where near its fullest potential. I took it to Brian and they custom tuned it -- went through quite a few revisions until they got it dialed in perfectly for altitude. I have a water/meth kit installed now and I hit consistent 3.9 FATS which for a PJK04 stage 3 at 6200 ft altitude with cats still on is pretty good IMHO. They could have tuned it more aggressively, but I wanted a safe and reliable tune that still put out respectable power.

Here's a link from a few months ago relative to my experience with Avalon. Hope this info helps.

Oh yeah, and what Wrinkled pants said -- while our cars are impacted being at high altitude, it affects naturally aspirated cars SO much more! It's nice actually -- cars that you can't compete with at sea level are now beatable cars up here. You'd have no problem beating Vipers, C6 Z06s, etc up here at altitude!

P.S. I'm not Chuck -- I'm Dante

Holy **** you got a sub 3 fats up here??

discuss further.

That was done on a stage III+ homebrew I guess. This time, Brian built some special sauce for me and I think I juiced the turbos a bit more. :-)

Brian was tuning it for me. Good stuff.
