k04 e42.5 selftune

[someguyondrugs]

stock k04 e42.5 peak boost was supposed to be 21psi 4k-5k but only made ~19





mods in sig...this is my first go at a corn tune.

try turning up the boost. you have the flow mods to support 20-21 psi easily. everything else looks pretty good

Why does calculated load never get above 2?

good call, didn't even see that......

If your targeting that small of a load, you won't achieve your boost targets. Once the load target is achieved, no more boost is required. At least that's the way I understand it.

Altitude probably coming into play here somewhat.

Just checking, Your signiture does not mention a TIP just the Cobb sf. Do you have both?

Boost toon, usually have no problems reaching load over 2 or 19+psi. This is the first run I've had on the dyno since I've started tuning the car, second time ever. Dyno log shows the pull was only 3.7 seconds vrs my wot logs on the mexican streets which are closer to 11 seconds. My original toon called for 19psi peak boost, I'm now calling for 21psi 4k-5k...just haven't had enough time to tune for it before the dyno day.

here is a recent street log on this same revision before I was on the dyno.

and uh...video for attention

You need something to cool your BATs.

I went with Meth and a bigger TMIC. I'll bet the high BATs are taking a lot of your power

Have you looked at how your VD changes with timing? You seem to hit high advance very fast....

Timing was increased slowly over 10 or 12 revisions, with positive increases in tq and hp.

Meth is going to be a necessity this summer living in AZ, but I have a few weeks of good weather yet.

Some of the guys at ES tuning recommended an EBCS...cobb specifically, saying I would make bigger horsepower...and if I actually hit 21psi I would. Going to continue tuning and hit that 21psi.

edit: alt was 2600ft in Tucson, I live and tuned the car in Phoenix @ 1100ft
