Road tune VS. Dyno tune
#16
that's all good advice! i went ahead with the dyno tune a few weeks ago. car feels great. more power and the turbo spools up quicker. the main reason i went with mike and not ed was because ed couldnt do the tune for three weeks (something about a hurt elbow) and mike fit me in same week. mike at gst did an awesome job though, i am very happy!

I would recomend a road tune unless you are trying to put out stupid high numbers. I have an 05 wrx wagon with a turbo back exhust and got road tuned locally in arizona. I love the tune as well, it definatly made a night and day difference in the perfomance of the car and I have raced many friends with 05 wrx sedans and wagon and have either been dead even or smoked em down and they all have been dyno tuned. So my vote is get a street tune for now, it is way cheaper and for small mods it makes more sense. When you are ready to do some real mod.s like turbo upgrades, etc. then i would say get a dyno tune to be ont he safe side.

Sorry about not being able to fit you in on short notice. I dislocated and fractured my shoulder in a skiing accident and couldn't work for about a month. Its finally healing up and I'm back up and running now.
As far as road tuning versus dyno tuning, I believe its possible to get good results from both assuming a good tuner and necessary equipment. I do believe, however, that any dyno tune should at least get logged and verified under real conditions on the road. Most dyno tuners around the country will start the tune on the dyno and then fine tune on the road. Sadly around the bay area none of the dyno facilities are in areas that would easily allow any logging or tuning on any roads nearby. Given the choice to work on a tune only on the dyno or only on the road, I would almost always choose to do it only on the road to make sure the tune is appropriate for real driving conditions and the customer's driving habits.
FYI, I do offer dyno tuning using the DynoDynamics chassis dyno at Speed Element for those who feel uncomfortable with road tuning. Note, however, that there is no appropriate place to perform any road tuning at this location. While its more convenient for me to use this dyno facility, road tuning is still my personal choice for the overall end result.
Some of the features of dyno tuning:
Benefits:
- Convenience
- Controlled environment
- High resolution power measurement
Drawbacks:
- Simulated environment
- Unrealistic airflow over radiator, intercooler, intake
- Sometimes unrealistic load curves applied to the wheels
- Lack of ability to test and tune quick transitions such as on sharp throttle movements and quick shifting.
Some of the features of road tuning:
Benefits:
- Real airflow over radiator, intercooler, and intake (no over heating short ram intakes)
- Ability to test and tune for quick shifting and throttle transitions
- Ability to tune overall drivability to accommodate the customer's driving style and habits.
- Much more involved and educational experience for the customer
Drawbacks:
- Very few appropriate and safe places to perform road tuning, which usually involves a longer drive to get to the road tuning site than it might to a dyno facility
- Small risks associated with driving the car in a spirited manner in a straight line.
BTW, I will be contacting some of the small airports around the area shortly to inquire about renting out space for road tuning. Aside from a private test track, I think that would be the ideal road tuning location.
Thanks

back to the topic the first time i posted i had 20 seconds to post
all things equil ie i have money and time. i will do both
i throw the car on the dyno and tune right off the bat.
if i stall it no problem no other cars to worry about.
dont have to pull over in a shady neighborhood and punch in numbers pull out start over
after its 95% of the way there then ill take it on the road to fine tune it

i say dyno if you want to be safe and know exactly what is working and what aint... Its to hard to try to drive and tune... A dyno is way safer and you know whats working and what aint.. road tuning is just what you think is helping... "I think its faster now" thats what you will be sayiing but a dyno you will know if you are making more power or not...my 2 cents
