help with air fuel ratio dynograph

[07BlownFoose]

I had a Guy tell me today that I needed a Mafia Maf extender for my procharger. He told me that may be the reason my a/f ratio isn't right...? I also noticed I have 2 bypass valves. They are the black procharger valves. Does anyone know why there would be 2 bypass valves? I need to make sure I have everything I need for pro Dyno to retune my car. Also has anyone ever delt with Amazon tuning in NC? I was told to check them out.

Stay away from Amazon...please.

Just call Dan and talk to him. He will tell you everything that you need.

Should look something like this..a fairly straight line. Your afr should be leaner if your NA...this is a S/C afr at 11.5 wot..

^Yeah, if you want to make no power.

^ seems a bit too rich. Are you blown or something?

Yes supercharged 11.5 @ wot....power is not an issue. I posted the pic to show OP how the afr line shouldnt be as erratic as his....not necessarily where his afr should be.

Ok. Makes sense now.

Called Dan and Made an appointment for next Saturday (29th). Hopefully everything goes well.

You should be fine. Dan and his crew will take care of you.

Here's my pics from down there

Let us know how it goes.

 

[07BlownFoose]

I will let you know. I will probably post a video as well. Dan told me I may or may not need the Mafia maf extender but if I do, he said he keeps them in stock.
New tune, spark plug change...I'm ready. It's killing me not to drive the car!

I am barely over 12afr on c12. You are "lucky" the AFR problem was down a bit lower in RPM/boost or you would have been picking thru the classifieds...

Finally got the car tuned yesterday. Dan did a great job. Dan changed my spark plugs and tuned the car. He didn't break any plugs and all the tuning went well.

1st pull - Dan cut this short at 4k, a/f was jacked up. running to lean.
2nd pull - 477.90 whp & 426.99 wtq
3rd pull - 463.84 whp & 441.07 wtq
4th and final pull - 493.57 whp & 450.41 wtq

Max boost was, if i remember correctly...12.4#s at 6200rpm.
Dan told me to keep it under 5500rpm just for longevity. I didn't need that mafia maf kit, but Dan did say that if i did any more mods to the car i would need to get the mafia kit and the GT500 fuel system. A short block unless I lower the boost. lol

Overall, I would have to say that I am very please with the results. Again Dan did a AWESOME job. He really knows his shit.

I know NO pics/NO videos it didn't happen, so here they are. Anyone who is friends with Pro Dyno on Facebook, you will see their post from yesterday.

Awesome! I am jealous that you put down mo' powa but I am glad Dan got your shit right! Another Vista Blue beast!!!

throttle response is so much better now. I am having to learn the car all over again. The gas pedal is so sensitive...I feel like i'm riding the clutch a little.

 

[Captainstr8edge]

They can adjust that if you ask.

I noticed that on mine too. I wonder if that is something he does.
