Tunes

[2004cobra615]

Who are you guys using for remote tunes these days? Looking for 93 octane and e85.
04 cobra 54xxx miles stock motor
2.9 gen 2 Whipple
Lethal budget return
80 ilb injectors
Twin 465 walbros
Stock lower

Looking for drivability as I dont track the car?

For 93 I would like to run the 3.5 supercharger pulley + stock lower

As for e 85 what do you guys suggest for supercharger pulley to make it to 22/23ilbs of boost?

I used 04sleeper. Malcolmv8 does tuning as well.

What’s your elevation?

That blower should make around 17 on the 3.5 at sea level. I saw 15 at 3800’.

Currently running a 2.9 upper and stock lower. See @21psi. Folks at sea level see @24.

Drivability is perfect on mine.

I'm at 500 feet above sea level.

So a 3.0 to 3.1 should give me my 22/23 boost range.

Sounds about right but you may be a touch higher. Seems like increase in elevation doesn’t have a linear effect on boost.

Do most people use a 3.2inch then?
