Please, please, PLEASE keep us posted! I would love to know what these can do for an NA build. Also, what other mods do you currently have and which tuning platform do you plan on going with, Osiris or EcuTek?

all of the conflicting things that you are likely hearing are coming from people whose "tuners" failed to calibrate/relearn the throttle bodies correctly. they will act a fool if you dont get that part right. everyone who has installed them, or had them installed properly, that i have talked to, are very, very happy with them. you will notice them when driving 100% of the time, as they add power/response even in non wot conditions... not many products are all that noticeable at part throttle, but these are.

I will. I'm not NA though. I'll have the AAM twin turbo on my car. I'm not certain what I'll be tuning with. Possibly Uprev for a while, then ECUTek. If Uprev steps up with some more features I'll likely keep it. We will see.

My dyno/tuning results
 

Ok gents, as promised, here are my results after getting a retune from Seb today. They are not back-to-back pre equipment/post equipment so take that as it is. Ill try and answer any questions I can for you.

Top graph is with EPS thottles and +20 degrees air temp from bottom graph
Bottome graph is from original tune about a year ago

Showing +4-5whp with 20 deg air temp increase

Over all I am very pleased with this purchase. Its not just the 5-10whp up top, its the more tq better response feeling down low and mid. I would not hesitate to recomend this mod to anyone that wants to spend the money. Just know that youll need a retune.

excellent work! and a very fair dyno of the product with untouched vvel maps. if vvel is optimized below the point when they start gaining in this dyno you will see those kind of gains all the way though, and more at those points. have Seb get in touch with me and I will consult with him about how to use this product to produce even more gains when combined with modified vvel events. again, great work and good gains for the mods you have.

EPS Tuning

Anyone with the Stillen Supercharger Manifold able to confirm this? Previous post shows that Stillen Supercharged guys were running 80mm TBs...

Which intake do you have and do you also have ported upper and lower manifolds?

Anyone able to answer this question as to what upper/lower intake plenums go best with these TB's.

I'm pretty sure I've answered this (not sure if it was to you or not but...). The best way to go about an upper/lower IM, is to get with either Synolimit or Synergy and have them port & port-match the components. For example [on my car], I had the manifolds (upper outlet/lower inlet) port-matched to each other. Afterwards, he ported the upper manifold inlet where it meets the TB outlet as much as he could without ruining where the gasket seals... from there, he port-matched outlet of the billet adapter that comes with the EPS TBs to the inlet of the upper manifold (and he double-checked that the outlet of the TBs were matched to the inlet of the billet adapter).

I'd say for an N/A car, this would be the best setup. You "should" be able to substitute the Motordyne/Z1 manifolds and have the same done to them, although I'm not sure how the Z1 is ported but I know the Motordyne is not. The results may change, or may be the same. The AAM manifold hasn't been shown to make or lose power (or do anything as far as anyone can tell), and neither has the RJ Mfg GTR conversion so your best guess is as good as anyone's for aftermarket manifolds.

Just got these installed. Was a very humid day but they baselined the car before adding the throttle bodies so you can see the improvement.

Dyno was on a Mustang Dyno.

Installed mods on car:
Injen Air Intakes
Upper/Lower ported intakes by Z1
FI Long Tube Headers
Magnaflow Exhaust

Attachment 122661

Nice pick up, and the curves look good. :tup:

I wonder how these compare with Synolimit's TBs?

I chose the AAM intakes because of the larger size to go along with the larger throttles. No porting

What kinds of gains did you see? Hard for me to justify 2000 plus unless the gains are major.

These are about $800.00.
