Yesterday I went to MV to test a new sensor for the A/F gauge. Still read 21.9. Then they plugged up their own A/F gauge that reads up to 16, and the car pegged that sensor too. They took a quick look over the install and said everything looks alright. They think the car really just is lean due to the tune. Of course, Doug doesn't think anything is wrong with his tune.

I'm going back next Monday. They're going to look over the entire install in detail and then dyno tune the car. More money spent...

 

MV is really good, I've heard nothing but good things about them. Thats why I'm not even going to mess with an email tune at all. I am getting my Vortech V2 intercooled today (Wednesday) I'll have it on around the end of November due to time and funds. I am going to take it to Mo's Speed Shop and have it dyno tuned then I'll come looking for you.


Keep us updated.

 

Well, a surprising find. The bung weld piece that came with the gauge kit was too long and not allowing the sensor to reach far enough into the exhaust to read accurately. They trimmed the piece down, and now the gauge actually reads correctly. It's off by a about a point at idle since it's behind the cat, but above 3k it's accurate. They said Doug's tune is on the safe side, but definitely a good tune so it was not worth retuning. The car put down 272 RWHP, 260 RWTQ, 11 lbs @ max, Mustang Dyno so a little underrated but not bad. Finally some peace of mind.

 

What do you guys think about the numbers?

 

Sounds about right. I'll be making around 340/315 @ 12

 

This may go without saying but are you still using the factory injectors? As far as I know most of those FI kits come with new injectors. I'm just taking a WAG at it here.

 

Everything is fixed now. They are aftermarket injectors.

 

what fixed it?

So are you gonna have to sell the blower now to pay MV? .
