Forced Induction SystemsDetailed discussions regarding cold-air intake systens, superchargers, turbo chargers, and other induction systems for your vehicle.
This is a discussion thread titled "JBA Headers.", within the Forced Induction Systems forum, part of the Technical & Vehicle Assistance Forums category.
Same truck would be better for sure but I dont think JBA wants to play ball. I figure if we do before runs at the same DYNO shop and after runs at the same dyno shop and we both put the same number of miles on the trucks after headers. Maybe something like 300 mile after headers give or take 30 miles?????
I am in north county but willing to see what can be done, right now i am looking for someone to do the install jba's speed shop quoted $470 so shopping around to see if there is anything better, for the dyno is it $104 each time the truck is brought in? Because if so $268 for gas and the time on the machine is a little steep for me to sport along with the install.
Give Richards performance in Vista a call. I just talked to Brian over there and he is going to take very good care of you TS guys. His install price was much less than that.
Their # is 1-760-758-7600 tell him you are from the forum.
sure, i went to the installer nick suggested and got a price i am willing to commit to, now if we can find something, closer, or less expensive i would be happy to take the truck in to by dynoed.
Approx 2-300 miles will allow the Ecu to relearn all the parameters.
Does disconnecting the battery and resetting the computer really help anything? And if so, does it negate the entire 2-300 mile period, or just shorten the relearning process?

It clears all the short and long term fuel trims and learned sensor baselines. To answer your question - yes it does, but it will learn faster from a hard reset than from readjusting existing learned parameters. Reseting the ECM can also avoid the likelyhood of a CEL, which can be triggered by an abrupt change in a sensor's reading from the installation of a bolt on part. Any change in airflow made to the engine (intake, exhaust etc.) should be followed by disconnecting the battery for a hard reset of the ECM.
All that having been said, it's not impossible to teach an old dog new tricks but it's definitely much harder

hi, on monday i had a set of of JBA 2011s headers on my truck by a professional.
i have a 4.7l 2005 double cab
i will contest many things.
1 the computer is relearning.
2 throttle response is immediate,powerful & aweseome
3 it is getting better and better every day, the more i drive it.
4 low end ,mid range ,and top end is ALL better.
my truck is louder , faster, and a much better throttle response.
if you look at the stock headers and match them up with the JBA, there is a huge difference. my installer said toyota should be ashamed of themselves. making such a poor product. 3 of the ports come out and go into 1 pipe. there is only 1 long pipe.
all the JBA are all the same size coming out of each exhaust port.
and such small size pipes.
i might have named a few things wrong, i don't know the technical names for everything.sorry.
but i do feel the difference.
and in my opinion worth every penny i paid for the headers and the install.
1 thing that is so very important.
i read this and went out and bought them for the proper install.
i would say no matter what type of headers you purchase, by OEM manifold gaskets!!!
### please buy the oem manifold gaskets ####
other wise you will be re tightening every month.
