Another great find from a post on evom made by Eric, of AMS. Here it is...
OK guys... the wait is over. Not only have we tested all the parts we have made so far but we have now made an astonishing 87WHP OVER STOCK!!!!!
This first chart is showing our EVO X stock compared to it with our Manual boost controller and MAF pipe / Intake pipe. You can clearly see that the gains are AWESOME!!! 45WHP from just a MAF pipe and a boost controller.
Boost was set to 22 psi and tapered to 16-17

Next on the list of parts tested was the AMS race series Catback exhaust. Again nothing was changed from above except the addition of the AMS catback. So the parts on the car up to this point are:
AMS MAF intake pipe
AMS boost controller
AMS Race series Catback Exhuast
Another 15 WHP Gain!!!!!
Here is a direct comparison between the Intake pipe and MBC and now with the addition of the catback

And now all three parts Vs Stock. This would be close to a stage 1 kit for a customer

Now we add another AMS product to the party. Its time to add a Test pipe to the mix. So now we are up to:
AMS MAF INTAKE PIPE
AMS Boost Controller
AMS Catback
AMS Test pipe
15 WHP GAIN!!!!! just from a test pipe!
Here are the previous parts compared with the addition of the test pipe:

And now everything up to this point compared to stock:

We are not done yet. How about we add on An AMS Front Mount intercooler. So now we have the following on the car
AMS MAF INTAKE PIPE
AMS Boost Controller
AMS Catback
AMS Test pipe
AMS Front Mount Intercooler
Another 10 WHP!!!!!
Not only did it pick up 10whp but the stock core would lose 5hp between pulls. The AMS FMIC keep the runs very consistent, fluctuating only a couple HP between pulls.
Here is a chart comparing all previous mods to the newly added FMIC:

And again all mods to this point Vs Stock.... amazing!

And last but not least is the AMS upper IC pipe. To be honest when we looked at the stock piece we all assumed this would be a strictly aesthetic piece and no real HP was to be made. Sometimes its good to be proven wrong.
The AMS Upper IC pipe for the EVO X not only picked up 5 more peak Whp peak but it made more power everywhere and as much as 10WHP in the MIDRANGE!!!!
So now to date we have:
AMS MAF INTAKE PIPE
AMS Boost Controller
AMS Catback
AMS Test Pipe
AMS FMIC
AMS Upper IC pipe
A pretty basic list of parts that is making 87 WHP OVER STOCK
So here we have all parts previous compared to the addition of the Upper IC pipe

And now the final Chart... the one we have been talking about here at the shop all day
Stock Vs the parts on the car now
87 WHP GAIN!
AND STILL STOCK (but safe) UNTUNED ECU!!!!

I Think its safe to say the EVO X is earning it colors nicely. Based on this I would have no problem picking one up myself.

Now, I'm sure that you guys have seen al the pics of these parts in the other ams thread, and now we have dyno graphs to go with 'em. I know, I know, your welcome.
