Let's see your fully tuned timing maps

[recompile]

OK,

I'm re-tuning soon, and I want to see how far off I am from a "very good" tune. I'm particularly interested in tunes that have shown strong dyno powerbands and/or good quarter mile trap speeds.

So please, post your timing map!

I'll start with mine that I'm running as of today (this is straight 93, I run 25psi, with a taper to 20 at redline... still on stock turbo, stock WGA, stock mani/O2. The Green in my sig is "on order", and wga, ported mani/hotside/o2 are going in a the same time):

I hope I'm not out of line when I say, damn thats a lot of peak timing, is that 14* peak? And at 25psi, must make for a fun drive...

100 oct. Mods in sig.

How did you work on timing map #2 and #3?

They are identical to #1

Razorlab, have AFR for that hex or dyno?

This is for 93 oct and 25psi spike holding 20-21 to redline.
(note - I changed the scaling on both axis so be aware)

[20psiMR]

100oct, just a 25psi spike but settles to 20. Dyno sheet in sig pic thread.

Here's mine. Tuned on E78 fuel at 28 psi with buschur intake, ams fmic, gsc s1 cams, 3" tbe, walbro 255, 1000cc injectors and gm bcs

dudical, I assume that square of 4-5° is for the two step? What benefit does that give you ?

12psi off the two step instead of 6-7 like stock.

So what kind of loads are you hitting @ peak and 7.5k ? Something like 280 falling to 220 ?

[C6C6CH3vo]

Dont have any dyno charts yet, but last year when my 4K - 6K rpm (3rd) times were 0.3 seconds slower it was 305/304 on a MustangDyno and about 5 psi less with a wanker tune without WB. I won't guess my current #'s until I go again

That is exactly correct.
