650/780/290 injectors, I believe I am your guinea pig for these injector sizes. I even put my screen name on the email I sent ya. And asked for the same things, except for TEMP 180-190 range, but I'd rather have 175-185 instead... and DWELL 3.50...
I also ordered the GT3071R which you told me it was shipping out today... U get a chance to ship it out? Email me a tracking number when you do please.
Thanks.

Ive been having a little trouble tuning my car with the Cobbs AP. I've read all the instructions and cant seem to figure out whats going on.
I start the car on the base map of MM 2005c MT Turbo v1.0.ptm and let the car warm up. The STFT is setting at -25% and when opening up into boost the AFR drops to 9.7 and and the STFT goes to 0% instantly and boggs down beyong belief. It isnt even drivable like that. So I parked it and swapped maps to the MM 2005c MT Turbo v1.5b.ptm thinking it would help the STFT. At idle the STFT was -24%. While driving, until I hit around 3k rpm the car runs fine. When the turbo kicks in, the AFR drops down to 9.7% again and the STFT at 0% while bogging down again.
What could be causing this? The stock greddy intake? any suggestions will help.

Unmodified Greddy MAF housing: no problem
Just picked up the Cobb AP(Tired of screwing with the Emanage Blue). Did my initial test runs and settled on MMs 1_3b map. The car doesn't idle perfect but it is idling better than with the Emanage. At WOT AFRs run from 11.6 at 3k gradually leaning out a bit to 12.1 at 9k, which for me is perfect since I've noticed that the engine seems to stumble a bit with anything richer than 11.4 above 6k. Just figured I'd throw in my 2 cents to maybe help out the community if I can. Oh and to MM, I've been using him as a guide for this turbo kit since 2004.

Engine Stumbling
[QUOTE=MazdaManiac;2465614]That is probably a weak ignition.
I figured that was the case. After the 1_0 map I tried the 1_3a and 1_5a and had the AFR stick at 11.1 all the way up to redline. If it wasn't for that stumble I probably would have left it there. Did a little testing with this AFR and then switched to the other map that leaned it out and found no noticeable difference in EGT. If I start to notice the stumbling again I guess its time to upgrade the ignition.
Thanks again.

Ignition
Coils are original OEM, plugs I just replaced about 1000 miles ago. Oh and if it helps the car only has 18.5k on it... I don't get to drive it as much as I would like.

Finally Boosted!!!!!!!
Its the space between the road and your front door. In some parts of the nation it has grass. In others, it has concrete. In others, it has old junk cars. You never know what you might find in someones front lawn...
