Maf Info

Okay,
here we go.
I installed the stock meter. The engine started right away. We had the surging idle syndrome. I changed the MAF table on the 1st 8 points and leaned it out. It took about 10%. Vola the car idles betterthan ever. It did not stumble at all up to 3000 rpm and than... forget the boost interferes and the MAF is done. So yes it will work since we already programed RT that we have 30 lb injectors.
The whole reason I did this because we have been fighting the evil gremlins for 3 weeks. The engine has been cutting up right around 3k right when boost starts.
I checked everything. Starting with plugs,wires,dizzy,cap and rotor all new now.
Ignition module it is new too. Fuel pump took it out and checked to see if it worked, it is new too. MSD coil is new. The thing we fixed in the meantime,
new headgasket on pax side. The list goes on...
So now we thought heck it has to be the MAF?? Since this is what started this whole mess to begin with. It disconnected itself from the plug or shall we say was not seated correctly and the problem started. Car would stall ,it would not start,etc. So when we realized 3 weeks ago, there is our problem,Plug the plug.
Yeah so I thought, It is fixed but... no it started this nasty cut out at boost.
So just to see maybe it was the SC and we unbolted the belt and same story engine just cuts out right around 3k.. So now I'm thinking fuel pressure hook a gauge to it and drive it under load. Fuel pressure does not go up and stays around 40 psi but will not go higher. I'm thinking possibly a bad fuel regulator?
I run stock pressure 39 psi and bumped it to 41 for now just to see it FP responds and it did. I'm still not sure though if it might not be my problem along with a bad MAF. Anyway long post since this is really making me go crazyy!!! I also checked the injectors and the seem to work good!! Anyway just venting and messing with Tweecer interesting to see that it will work with 30 lb injectors.

Okay,
problem fixed for now.
After contemplating on all the things I had already gone over and over.
I decided to look at the FPR and it was hooked up wrong, not even close to any vacum signal. I in my ever great Technical wisdom thought the problem was solved?? However test drive results were negatory and dissapointing. I was
actually fixing things but not the main problem. So again I hooked up the code reader and bang 2 new codes popped up 211 and 212. PIP sensor related.
That dang distributor that we replaced from AZ with life time warranty 3 weeks ago was the problem. I could not believe it ,the dizzy we installed thinking newrebuild or whatever was a dud all along and made me curse and #$%@,anyway this had caused all our issues cutting out above 3000rpm.
So in closing, I 'm running stock MAF right now and it idles like a stock out of show room 1995 mustang. I know it is too small with all the modes but it is kewl to know that before you spend bunch of money on new MAF and in conjunction with the Tweecer you can make HCI and blower run but dont get on it until you run a
WB. Anyway we will be buying a PRO-M since I heard only good things or maybe even a lightning maf. I will not buy another summit MAF though until they can provide some more detailed flow numbers etc..
So right now all is well in MAF land and very soon we will get some dyno numbers with this combo.
