Thinking about making a full Intake Manifold Replacement

I feel that you have no experience with standalones & your statement will cause confusion. ANY standalone (AEM EMS, Motec, Haltech) will be 1000 times better than ANY piggy back. I guarantee you that you can get more power with a stanalone. And as for standalone being to much $ for just a turbo kit, when do you feel you should go with a standalone?

let me clarify then, so as not to mislead people. The majority of people on this forum have an NA and will always have an NA setup, even those that go turbo will more then likely stop at the 8-12 psi level. That being said if you have a stock engine with a turbo on it I don't see you getting much out of a stand alone system, certainly not for the amount of money and work to buy it install it and have it tuned. Yea sure they are 1000 times better but only when engine parameters change. I feel a standalone would be needed on a fully built engine, with adjustable boost levels, longer duration cams, bigger valves, these kind of components. If you look at a lot of the tuner cars, you tell me how many of those cars go stand alone. Very few, because of all the work associated with the setup. The majority of the other tuner cars like SRT4, evo, sti all of them go to a reflash or piggyback system.

Yep.

the main reason to switch to a standalone is when you start using sensors that the factory ecu can't handle. i.e. vein pressure instead of the normal MAF or MAP sensors and other situations like that. Until you have a fully built race car I would say your thousands of dollars would be better spent elsewhere.

I agree this point a stand alone on a NA setup is not worth the $

even those that go turbo will more then likely stop at the 8-12 psi level. That being said if you have a stock engine with a turbo on it I don't see you getting much out of a stand alone system,

Here is where I disagree. A piggyback system modify existing parameters that are in a ECU. It has limits, On a scale of 1-100 you can only adjust from 35-65. A stand alone allows the user to start from scratch. You can adjust from 1-100. You have full control of fuel & timing. You are not modifing an existing parameter.

certainly not for the amount of money and work to buy it install it and have it tuned.

This is the main reason most Yaris owner will never truly know the potential of the 1NZFE, you are tight in the wallet. That is the reason most Yaris owners bought a Yaris. Its a inexpensive car. Speed is determined on how much $ you are willing to spend correctly.

Yea sure they are 1000 times better but only when engine parameters change. I feel a standalone would be needed on a fully built engine, with adjustable boost levels, longer duration cams, bigger valves, these kind of components.

Pistons, rods, adjustable boost levels, bigger valve are not the reasons to go standalone. Full adjustability, safer, more reliable, faster processiing speed, On board data logging, knock control & it makes more power.

Mabey in Phili piggerbacks are mostly use but here in the MIA STI, SRT's & Evo's that are making real power are all using AEM EMS. No they do have an advantage, the AEM EMS replaces the factory computer completly.

These are good points.
I have a custom-wired MoTec in my fully-built Scion tC. I did that because the piggybacks didn't give me enough control, as noted above. Last tune netted me 443 whp, 474 torque -- not bad from a 2.4L street car. And more room to go even hotter.

But.... it was friggin' EXPENSIVE to do all that!!

I will never go that far with my Yaris motor....but I hope some people do.
