Exactly. The fact is that people these days are way too concerned with a max power number. I'd hands down use a dynapack to TUNE a car. Who cares whether it reads 180 or 200 HP at the beginning if you're just using it to get an idea if modifications / tuning settings are adding, or removing horsepower?

Nice numbers!!!! Where did you dyno it and how much did they charge??? What are you using to adjust AFR?

i dyno'd at fast specialties in vancouver washington. 60 bucks for two pulls, but i got 5 pulls for 60 cause the tech there was amazed by my car. they are great people and they love anything that goes fast. i.e they dont hate imports! ha! i am not adjusting my afr, that numbers is on the factory ecu. i would like to get a mugen or spoon ecu but nobody will give me much info on these two products. good to hear from you wyatt, cant wait to see your car when shes done!

i see where your coming from in terms of tuning a car, but to see what peak Hp is i still go with a dyno jet (like version, no tiuning just numbers). How ever i lack to see the point of using a non-loading dyno to tune. My tuner, who is AEM factory trained does the entire car on the street/garage thats why i lack to see the point of using a dynapack, why do you need hp numbers to tune?? we tune for 100% safety/what the motor likes with in safe limits.To do this i should mention that we use a Tech Edge wideband 02, it retails for $2K the sensor it self for 700.- its scarey accurate. The harness used in it has resistors all the way through it so each wire is perfectly matched the harness goes for 800 by it self. Im not saying money=greatness, but for the majority of this indusrty "you get what you pay for" typically apllies. The thing i like most about tuning with out a dyno is that you dont run into a greedy tuner who will sacrifice safety for power. Im sure this idea of street tuning will make most very sceptical but my tuner is absolutely great, he has tune many of my freinds cars perfectly, including my frinds turbo S2K which is the fastest in the US right now at an 11.3. It has 1000cc injectors and runs like stock its fabulous!

just my thoughts,

Please let me know how you tune a turbo car on the street. On a dyno you can simulate load for as long as you want and keep the car in every "window" of the fule map for as long as you want. SO you can have for exs. 40%load at 8000rpm. Try this at the street

do an extent we do what you are saying, the reall trick is to be good at math. You can get a fuel map about 60 to 70% right after you set up idle and know the AFR at idle, if you know the math. i understand you were just giving an example, but why do you need to hold a car a 40% load at 8K rpm, when you can hold it a 40% load at 4K or 6K rpm?? it comes down to how you want to go about tuning a car, there are multiple ways to get to the same end result.
