As some of you know I have been going through a lot of trial and tribulation with my setup since I put my car away for the winter about 9 months ago. Prior to that I installed a ported FAST90/NW90 in addition to rephasing my cam andhaving the heads milled to -.030". I had previously had an LS6 and ported 75mm tb on the car. It ran ok before I put it away, but upon taking it down it ran awful, wouldn't idle, would stall, etc. I had lot's of problems and tried as many fixes.

I had stopped scratching my head and asked for ideas on this forum. ONe of the suggestions was to put it back to SD and re-scan due to the possibility of the MAF masking some issue. I did that and retuned my VE table, to a point. Yesterday I booked time on a Mustang dyno so I could do real world loading on the car and drove it on the dyno to set up my VE table without worrying about the LEO's coming down on me. I found that my VE table was still out of cal quite a bit and got it tuned in with 2 runs to fill the tables. It toolk about 1 hour of driving and tuning to do this. Then I plugged the MAF back in and re-tuned that to the VE table. That took about 15 minutes. Then I did a bonzai WOT throttle run from 1000 to red-line in 4th for PE. That got my AFR nailed in.

The long story short, the car is amazing. It runs BETTER than stock. It idles with just a hint of lope, doesn't stall at all, has great throttle response, and is awesome at WOT. LTFT'd are withink 0 to -2% for now, more driving needed, but all I can say is I like my car again. I'm even taking the wife for a drive later today. The hell with the gas prices. I'm making ~30mpg with 4.10's .

This is just a thank you to the guys on the forum that helped with all the suggestions and ideas. Also, it's validation for the REQUIREMENT to have a solid VE table as the basis for your tune. What happened was I didn't redo the VE table after the FAST 90/90, and assumed the change would be linear and therefore could be compensated for with RAF adjustment. WRONG!

I'm still very new to this, but I learned an awful lot by having gone through this last tuning experience, probably more than I should have, but that is the bonus from having a tool like EFILive.
Thanks again EFILive and the forum.
