So what is the easiest and least expensive way to get a stock evo to make about 300bhp, rather than the 271 that they come with.

 

WORKS ECU re-flash. $450

 

I'm gonna go out on a limb because I don't know exactly your definition of "easiest". But I'd say, intake, full turbo back exhaust, and maybe a fuel management ECU.

BHP or WHP?

 

I heard it was enlarging the exhaust manifold/turbo gasket.

Please don't take this post seriously.

 

One way is to install an SAFC2 and a MBC.......

 

ECU flash

 

The easiest way would be to get something like the RMR, Real Engineering, Vishnu, or WORKS ECU upgrades.

 

the easiest way if you dont give a **** is the crank up the boost, set it at 22psi and you'll have about 300bhp, not for long tho

 

Trying to get 30hp out of ECU mapping alone is going to be a substantial compromise to margin of safety against detonation. And on 91 octane, I'd go so far as saying that it's close to impossible to do with any degree of safety/consistency in mind.

FWIW, it's not hard to get big numbers with one cool dyno pull on an agressive mapped car. Back to back, however, the situation takes a turn for the worse.

And yet, that is exactly what we have achieved. I'm happy to report that our extensive R&D has enabled us to provide consistant, safe and reliable, not to mention, repeatable, 25-30 rwhp gains with our Brain flash program -- all this without even touching the peak boost.

Let me re-state that. I was talking about real hp, not dynojet hp. We've seen 25 dynojet hp gains as well with the XEDE as well on custom tunes at various dyno days. Emphasis on the "custom tune". And that was when the XEDE, like your reflash, couldn't control boost. I'd suggest a/b testing your baseline reflash on more than a couple cars. I think you'll see that car-to-car variance (which is as great as 20-30hp among stock EVOs) makes it quite impossible to repeatably see a fixed 25-30 wheel hp incremental improvement.

I heard that you can get an upgrade kit from mitsubishi direct that you can push 301HP

 

Not in the US. In the UK, howevedr, you can purchase an FQ-300 kit for approx $3200 (USD equiv). AFAIK, it consists of exhaust mods and engine control unit remap.

Are you saying less gains for more hp cars? I thought all the ecu's factory maps are the same? Or the differences is caused by engine tolerences? Geeze, talk about cracker jack box! Not knowing what you get until people run their cars to check that they don't have the old GSX 4G63 engines

 

Talk to Alfred...he has the best evo in the states and his makes crazy power....pm him and ask him what he did first and how much it'll cost.
