Do you have your car back Rolex?

"When a MAF works like it should, (i.e. a TRUE MAF chip and not a crap massaged AFM signal.) then it can calculate how much fuel is needed by how much air is being pulled through. AFR stays the same whether you are running 12 psi or 25 psi. (. . .as long as your fuel system is capable of providing that amount of fuel, of course"

Ok, 2 points on that.

1. Why can't the stock AFM do this based on how muc hair is flowing past it and due to the rising rate FPR.

2. My mech. says that what I jsut said IS possible with stock set up. Turn up the boost, the fule will adjust accordingly. Just keep adding bigger injectors and you are fine. And he speaks from many years of track and street experience. BUT no one else in here says that it is posisble in stock configuration.

Anyone prove why this is not possible in stock/AFM set up?

Rolex: ok, no problem

Todd: Honestly, the best person to fully address that would be John himself. That's just my two cents....

Sam: Yes I got the car back. Been very very busy with work, and now its cold here. Damn!

Tms951

todd, an afm can do this but not as accuately, which means as safely, because it only measures flow and not desnity. Because a MAF can measure density it knows exactlyhow air there is and how much fuel to add.

I don't know about you but I would not want to keep turning up the boost if the ECU was only taking a good geuss how much air there is and adding around the right amount of fuel. Sounds like a disaster waiting to happen.

Did you measure your A/F ratio when you were on the dyno? You may be running waay too rich or waay too lean.

porshhhh951

umm...you got major issues.

get yourself some of johns chips that include the hole new board mapped for the maf..but, I think you also might have other things going on

I made more hp and tq than you on 1psi with a much much much smaller turbo

Sorry to get so off topic here. To add to what tms951 said, the stock AFM is designed for stock boost on a stock turbo. Upgrade to a larger turbo and it is very easy to max out the AFM.

biggles,
Don't be too upset about the numbers. Most people fail to realize that to make big power, everything has to be perfect. There are some people on this site that make it look VERY easy, when in fact it is not. Let's take a look at your graph and A/F (if you measured it) before you start writing checks. THere are many things it could be. Depending on how the graph and your AFR look, the first areas I would check are the clutch and for header/crossover leaks.

well said Ted.

You results aren't bad. What T04E do you have? This means alot. I'm sure with your present hardware/software if tuned right can give you good results. BTW check you boost gauge. Make sure that 18psi isn't 16psi. Some mechanical gauges suck.

snappy

hmmm, what part of the stock AFM makes it max out so soon,
I have seen close to 380RWHP on a few occasions on cars using the stock AFM.
it must be the software then but definitely not the hardware.

Get a reputable shop to get your car on the dyno and burn you some good, custom chips. At 18psi with a T04E and the likewise upgrades you have, don't be surprised to see 50whp more than what you have.

biggles

I will have to load the graph tomorrow, my membership had apparently expired, just renewed but unable to validate. As far as the turbo is concerned, I think it is a TO4E, .60 with a 8 hotside. My biggest concern is knowing that the car is set up right and properly performing, not trying to make HP'S, However will take all I can get without blowing too much cash.

you should be getting close to 360rwhp with that setup running that amount of boost. i second getting someone that knows there stuff to fine tune it. ask around for some recommendations for someone in the Norfolk area or where you live.

Danno's chips are some of the best... regardless of his business practices.

there are several people he did custom chips for that never worked properly, myself included.
