I had tuned this Evo awhile back and it made 275 whp / 251 wtq on 91 oct, with the stock FMIC and stock cat.

Retuned it this time on 91 oct with the addition of the FMIC, Test Pipe, a COP and moving from a 2.75" DP to 3" and the car gained 40 whp / 36 wtq which was pretty amazing for the small changes.

Next up was the E85 tune and like always, huge gains!

+ 53 whp / + 69 wtq

Solid is E85 @ 28psi, dotted is 91 oct @ 24 psi:



For reference on our dyno:

Stock 03/04 evo = 190-210whp

Stock 05 evo = 210-215whp

Stock 06 evo = 220-230whp

Stock 08 evo = 215-230whp

Stock 09 Ralliart = 190-199whp

 

Nice work Bryan. I did end up confirming your MD reads a touch higher than mine. That occured running Ben's car. Even the untouched dyno's still read different.

Yes Ben told me. The difference can always be contributed to dyno setup, temp, different days, etc. One of the various reasons why all dynos can read different.

We had a local Dyno Dynamics that would read SPOT ON with our dyno on some cars on some days, and slightly off on other cars, different days.

I always try to include before/after with all the results I post.

I would like to put E85 in my car with a tune. What exactly do I need to upgrade to SAFELY run E85? Any help would be greatly appreciated.

 

For Evo 8/9 all you need is a walbro FP and injectors.

nice work Bryan!!!

 

pte 1000s would suffice w/ a stock turbo ix, obviously with a walbro right?

Indeed

Great job as always, Bryan!

We need to get you out here on the east coast at some point!
