WOW~!!!!!!!!! :naughty: :naughty: Finally, I got tuned by Scott with EcuTek. My car is SUPER smooth now. The power comes on SOO smoothly and early, I barely feel the "BANG" that i used to get when the turbo kicks in. Peak boost is around 19psi and tapers down (just like most other other people). Ecutek pulls harder and smoother than my previous AP Stage 2 map. I love it!!! I went to SOG around 8:30am and was done by 6:00pm. It took little longer than I expected, but it was all worth it. Scott took his time without rushing anything to make everything perfect as possible. No surge, SMOOTH AFR, HARD Boost, and COOL EGT. I love it!! I LOVE IT!!!! oh yeah, i add another "BLING" along with my ecutek. USDM STi TMIC. It's all scott's fault. haha Now i gotta get STi scoop and splitter. More money again. This addiction will never stop~!!

good to hereyou got it tuned chang. thats comming up very soon for me. got a few more things to do befroe i get ecuteked so i dont have to waste additional money on tuning when i do the new turbo. you dont have an after market turbo do you? what kinda of numbers did you pull?
Awesome man! It was great meeting you up at SOG yesterday. The car looks and sounds awesome. :bigthumb:
Thanx clay. I wish i dyno it, but the time ran out. Scott and I decided to spend more time on road tuning due to turbo surge from smaller restrictor pill. I guess we'll find out on the next dyno day!!
Little Update with my ecutek. I began to have surge at 5th gear couple weeks ago. Now there is random 4th gear surge. So when i'm cruising on highway near 75mph and floors WOT(5th gear around 3k rpm), boost shoots up to 21psi then comes down to 17psi and it repeats couple more time. Around 4K~4.5K rpm, it settles to 19psi which was tuned for. Oh well... I'm being little lazy with contacting Scott. This really took away my fun highway pass...
But..but...everybody says ecutek is perfect. Heh, just kiddin'... maybe you have a leak somewhere or a loose vac line or something. If there was a problem in the tune you'd think it would have shown up sooner. Let us know what you find!
Are you using the stock restrictor? I am having similar problems (4th gear boost surge) with a smaller restrictor and Prodrive Stage 2.
I have smaller restrictor which scott installed. Before I forget, i'm gonna call him up and schedule appointment. I remember him saying that he will touch down some wastegate duty little bit.
Good idea. Yeah, Scott said that a smaller restrictor without adjusting the wastegate duty cycle could cause surge. Unfortunately, right now, Scott can't tweak the Prodrive maps, but Prodrive should be unlocking the maps very soon. For now, I'm leaving the small restrictor until the upgrade to PPP3. Good luck with the car and keep us posted.
Chang, Hey Buddy, I called you back this morning (on my layover from tuning in Canada), but no answer... Your first post is so happy, and now you seem a bit upset about this. I apologize about the 5th gear surge, going with the really small restrictor makes it harder to prevent surge, but all you need to do is stop in and I can have you back to smooth in no time (one hour at the most, at no charge of course) - "My car is SUPER smooth now. The power comes on SOO smoothly and early, I barely feel the "BANG" that i used to get when the turbo kicks in. Peak boost is around 19psi and tapers down (just like most other other people). Ecutek pulls harder and smoother than my previous AP Stage 2 map. I love it!!!" I want you to love it again. I can do you this afternoon, Wed. morning or Friday morning. Give me a call. SS
On friday, Scott did couple touch up on my map. Now it's SMOOOTH again. Surge is GONE!! I hope that it'll be never come back. :wavey: Since i had little free time, i decided to get dyno done. Guess what?? I got 251wtq and 231whp. I gained HUGE 28wtq but gained only 4whp compare to my accessport. BUT, my accessport dyno was done at TopSpeed in this spring, and the temperature at SOG was 15-20 deg higher. I think DynoJet (TopSpeed) usually reads slightly higher than other dynos, but not sure... Thanx Scott!!
ECUTEK vs AP Stage 2 Disclaimer : These two dynos were done in TWO different dynos and TWO different days. ECUTEK dyno was done at SOG with DynoPack and AP Stage 2 map was done at TopSpeed with DynoJet. The temps in SOG was significantly higher than TopSpeed due to weather.

chang: looking at ur plots, i notice the ecutek makes much more power at lower rpms but at higher rpm, AP seems to make more power... im inclined to believe this difference in power up top is because of the boost taper scott has set on ECUTEK... looks like AP is running higher boost up top... do u know how much boost AP made past 5000 rpm?
The AP doesn't make any more, it just doesn't make much less... like you said though, they may not have had such a "safe" taper in it... (mumbling) more power then mine.... (mumble, mumble) we'll see how much power that Super 16 makes now.... SS
i agree... more reason to make more power throughout the band with ecutek... thats y i wonder how much boost AP makes past 5k rpm
