" Wow, I would not expect a small 2.7L V6 to be putting out power like that. Ive always been questioning the V6's in the F150's but it seems its putting out more power than my dads 5.4L V8 in his F150..and 700lbs less is pretty impressive.
100 per every other tune to send the same file and over is certainly not doing anyone any favors. Go look at the DL counter of Terrys tunes on N54Tech, than multiply that by 28 revisions, x 100 for half of them. We prob could have bought him his two M's from just the "custom tunes".
You mean $100 when you want a custom tune from Terry for a different octane or turbo or just for a revision? "
" The turbo stops making power over 6500rpm so I just stopped revving it up. We shift it around 6000rpm.
On the timing I found 6 degrees to be a pretty good MBT value for it. From 6-11 in 1 degree increments there is basically no gain all else being equal. Dropping below 6 started to drop power a bit. The pump map I ran on the same curve which produced the best figures but a curve of around 5 degrees would be more appropriate. We are evaluating using the same curve with a little less aggressive boost curve. Because it will simplify things for the end users if the same back end flash can be optimized for both on and off meth, allowing on the fly map changes where the JB4 changes the boost profile, IAT decay, and fuel trims, with no need to swap flash maps to optimize either.
The 3.5 bar map is required for > 21psi. In the JB4 we've also made the 3.5 bar map sensor the "setting" to enable the larger turbo maps. So you'll need it if you plan to run the maps shown in the dyno. Although technically speaking you could just make your own map 6 boost profile values (below 21psi) without the sensor. "
