My Positive Exp Tuning AEM EMS S2 on Stock Turbos/Fuel - 313//337

[bboyalan]

I usually keep my more mild tuning updates to our regional board, but I felt that this build has had a pretty cool outcome thus far.



The owner, Rob, was referred to me through another client/friend in SoCal. After seeing the results with "DuTTch" Mark's VR-4 [560AWHP @23lbs on AEM], he decided to hit me up. I knew that I could not pass up the opportunity to tune a Series 2 from scratch yet alone with a stock turbo and stock fuel car.



Needless to say, I was determined and very much prepared. I was already on my toes from doing multiple GReddy/Link/ECUFlash tunes and such this year with local 3/S, Evo, and DSM cars. The results absolutely surprised me, and I can honestly say that the car drives leaps and bounds better than it did on stock ECU/MAS!





Full boost by 2.8k, crisp DFCO, lean cruise, and she looks/sounds/performs plain mean! The only downside was that I quickly realized how limited I would be from the stock fuel system - completely tapped out! I was amused to learn that shortly after receiving the car back, he had wasted no time in acquiring GReddy 720cc injectors and a Walbro 400lph FP yeeee!!


"313AWHP is the final number - for now! This is exactly what I was aiming for on stock turbos, stock injectors, and stock fuel pump. The gains are roughly +38//22 at the same 1bar boost with pre's hollowed and 3SX DP added along with fine-tuning the AEM of course. I am definitely content despite not having more fuel to work with.

For the record, peak KNKV was ~1.09v =]"

The next possibilities include more boost on Pump-91, 91/100 mix, or Pump-E85 regardless of stock or upgraded turbos. Things will continue to get more interesting to say the least though!







Stay tuned!
