Want to eliminate your MAF?

11.5 is what most people tune to including myself on pump.
11.7-11.8 is what I have seen on some agressive reflashes from tuners names withheld, which may have had some knock.

I just put 11.5:1 in the AFR tracking in the Pro and let it do the work..... 
There are 2 PnP harnesses we have been discussing.
Joey has the Speed Density PnP which handles the sensors. He finished the remaining connections himself similar to the way an SAFC installs.
What Joey wired will become the second PnP as soon as I can get Boomslang going. Probably a couple weeks, and they get 140.00 or so for their harnesses.
Otherwise everything you need is ready to go. The units in stock are not currently flashed with 4.2, but I can make sure yours gets flashed before it ships.
I'm not sure how many are left in stock, its been a busy week. You would need to check with Mike. (he handles that kind of stuff.....)

I would only get the boomslang if you don't want to cut into factory wiring harness. The install is pretty simple, I figured it out fairly quick.
Bob if you run out of stock how long does it take to receive more?
Don't forget that the boomslang is not needed, you can use the standard fields harness and still not cut the factory wiring if you can solder. The fields harnesses I have seen for under $100! PM me if anyone is interested in the standard one.
you can eliminate fuel cut without the reflash by oversizing the injectors....
If you want to run leaner, you can boost higher without the fuel cut as well.
But a reflash is a good idea anyway in the long run.

there is only one wire cut, and it is the same wire you cut when installing an SAFC.
We are looking at under 2 weeks at the moment. "Standard" leadtime is 2-4 weeks depending on a bunch of factors....

This of course is assuming that you are not at or near the pump gas threshold for knock 20-22psi as it is. You do not want to increase boost further at that point.
I concur, until the timing adjustment feature is online, this sounds like the best course of action to bring timing numbers into the correct range.

How much is the timing increase? A modest injector upgrade should not cause too much timing advance. Anyone have DATA?
Perhaps running some more timing, and a little less boost would be faster.... (EVERY group debates this one!)

If you want to raise the fuel cut level, 25% larger injectors seemed to do the trick with the S-AFC and should also apply to the MAFTPro and anything else that uses MAF signal. The only problem I had with the larger injectors with the S-AFC was the idle fuel trims would generally go close to -20% so if you were driving for awhile at part throttle, then came to a stop, it would run rich until the STFT's would readjust and bump the LTFT's. Unfortunately if your A/C was on, it would run really rough when that happened.
Hope this helps..

show your support let the moderators know you think MAFTpro needs its own forum.
