My Turbo Kit Experience....
I have seen differently. The MAF and flash up to about 350 whp on the stock turbo will make the same HP levels as the AEM EMS with speed density. After 350 or so WHP we have been able to make fairly substantial gains in HP using the EMS and speed density.

I am so confused

The former hasn't been an issue with anything I've tested (up to 600whp on an AWD Dynojet). Neither has the latter since neither I (nor anyone I know) have ever been able to measure any appreciable vacuum between the factory air filter and the turbo inlet. So if the combination of factory intake and MAF induces negligable restriction, the MAF, by itself, also offers negligable restriction. This issue sould be put to bed.
To date, no one has been able to offer any proof that ditching their MAF has yielded improved spool up. This is because it doesn't and no one has been able to bend the laws of fluid dynamics
Ditching a sensor that actually measures airflow for a sensor that only estimates it isnt a good move unless you remove inherent system limitations while doing so. In the system descrived (600whp and below), this is not the case. However, mapping a stock MAF'd EVO with larger injectors, GT35R at 30psi isn't something that everyone knows how or has the means to do. Whereas doing with a stand alone is easy as pie. The hard part with the stand alone, however, is to keep the level of drivability and adaptability that we've seen possible with a MAF-based system. It's certainly possible but it takes some deep pockets and a lot of tuning time

Just my 2c,

I'd love to try an XEDE, want to sell me one? I'd like to start installing and tuning with them as soon as possible.

Cheers,

Shiv,
This Exede, you are the sole importer of this unit right? How many shops are you re-selling to now?

I don't have the dyno yet, so I guess I can't get the Xede.
jj008, stop by and get the EMS, I'll install it and tune it, if you aren't happy/impressed when I'm done I'll take it back off.

WHat about UTEC? I mean if all these piggy back units just change the inputs and outputs of the stock Ecu, they why can't a flash offer the same whp performance? I mean I understnad that some piggy backs have 2 setps and the ability to LOCK OUT certain CEL's and do stuff like that but the overall interpretation and manipulation of the a/f signal, what is lacking in a flash?
I am SERIOUSLY looking at UTEC as it is 50% the price of teh EMS. I WOUDL OWN an EMS if it was cheaper, too expensive IMHO. Hell even used they are too much
