Once you get a TBE, MBC, and filter, now that's a WHOLE different ballgame.

couldnt agree more(my exact mods) until my gt3071 is bolted up, than I will pay for john to come down personally to tune this beast, even if I'm the only one he comes for, ill make it worth his while.
Buy him a ticket + food + lodging + custom tune fees and I'm sure he'll come out. 
I'll ask him to see how much you're looking at when he tunes my car (along with a bunch of other Evos) for a one man tune. It'll be much cheaper for you to get a custom tune group formed up.
So you live in Irvine? Great place. I used to drive there all the time to meet up with my friends when I lived in Diamond Bar.

John is the man. Car runs like night and day difference! I have a custom flash from John. He also flashed my 2003 evolution before the white one.
My car runs awsome since the flash or flashes I should say.
I just added a meth kit, some timing and a clutch. She's deff. a 11 sec. car now. Just needa break in the clutch, and off to the dyno and track...
John is even better at road tunes. So if you can. I m lucky he lives like 15 mins away from me....lol, get him to road tune your car.

I have a dyno tune form John at the moment. Since there is a slight change in my modding path in the next week or so we are going to go out for a road tune. Ill make sure to have DLL hp graph before and after for just a reference and post up somewhere in a thread.
And yes, John is the man for tuning. Either e-mail, road, dyno you can't go wrong.
Jestr Tuning On Evo 9
This guy is the man mann ! He did my evo 9, with TBE, intake, Mbc, fuel pump, and didnt regret going to him one bit. His tune runs so much smoother that it feels like stock. His tune ran smoother than my previous dynoflash mail in..

Awesome man, I think his tuning is worth it.
I live in shady canyon, right in the middle of newport and irvine. But I love it, its a really nice place. Next time you are in the area let me know and we can meet up for some highway runs, theres a new canyon road that used to be(still is) the old 133 going down to laguna, looks like its gonna be fun!
I had great experience with him as well. He sent my map right away and then after I loaded it and saved a log from the car, I sent it to him and he made some fine adjustments and sent me another revised map for no extra charge. The car feels great and isnt knocking. Best $50 I ever spent on a car.

I agree Ruben, had the mod1 flash allot better than the stock hands down. Had John road tune my car...HOLY SH*T!!!!!!! Big Big difference...its nice that he lives so close to us
Good guy great service!!!
John tuned my car and the results were amazing. I rooted up everything I could find on John before I gave up trying to find something bad about him. His work lives up to his reputation - this coming from a former tuner myself of 7+ years!
Good man and he know what he is does for sure. I too have an Evo IX and before and after is like day and night + he is 3 miles away from my house
