Tacoma 2011 4x4 V6 AT DC LB.

2nd run :

Adding of TRD SC and ECU reflash. No other mods added.
Results 281 RWHP and 295 lbs-pi.

3rd run :

Another important data, i've finalized my boost gage installation. I've not done a run to the cut off but at first sight it seems thet i reach 7 ( correction in fact it's 7.5) psi of boost.

This way I now know exactly what the gains are with the spacer alone, without clouding the results by making other concurrent changes.

Just curious how accurate the numbers are based on which type of dyno was used (Dynojet vs. Mustang). I know there are many factors that can affect the ending numbers, but I am mainly referring to differences / variables between the 2.

I might be getting my Taco dyno'd soon, and will likely go with a shop using a Mustang MD-250. This shop was recommended to me, and for good reason http://www.bloodenterprises.com/
I am also thinking about going here: http://www.turbotechnologyinc.com/site/?page_id=5. They use a Dynojet and have also been recommended.

Here is some good info.:

Wow, this thread has been immensely helpful. I have the TRD exhaust (truck is just coming with it) and was planning on the DTST headers, y pipe, some sort of air intake modification, and a good programmer. My goal is to put down on the ground what Toyota says these 1GR's put out at the crank (about 270 lb. ft.. couldn't care less about peak HP)...and keep it all as low rpm as possible.

Also good to know that all these mods will help if and when I pull the trigger on a s/c.

Thanks guys!

Same boat I was in.......... but I went 3" exhaust and long tubes.

Drove terrible IMHO, the TQ wasnt down as low as it used to be due to the excessive free flowing exhaust.

Do 1 mod at a time just in case.

That MotoIQ article was very helpful.

Yeah, I plan on spending a lot of time on a dyno...it sounds ridiculous in a way, being that I'm going through a lot of work on "just a truck" but I know the importance of volumetric efficiency an have seen first hand what quality parts can do to an n/a motor when I built up my VQ30 back in the day. Dyno just verifies that you didnt waste a bunch of money for nothing, and allows you to fine tune to get the most out of your $. I'm a fan of that hehe
