So here are my mods:

Cattman headers/y-pipe (no cats)
NWP IM spacers/VIAS block-off plate
Unorthodox stock diameter pully
Greddy SP2 exhaust

Did 3 runs with a Fujita intake, and 3 more runs with an R2c prototype intake.

Here's the average:

The dyno guy mostly does Fords etc. but he did see that I was running pretty lean because of all the bolt-ons.

So it looks like an SAFC2/UTEC will be needed?

Also, is anyone aware of a stock 6th Gen that was ever dyno'd?

Pretty decent numbers actually. What does the AFR look like?

[Oolatec]

Way outta wack. Pretty lean. But it may be due to an intake leak... I need to get it looked at real soon because I've been running with the P1283 for close to 3 months...

Interested to see what kind of numbers you'd pull after a tune

When I find a shop I feel I can trust to tune this thing... for sure!

It's going to be leaner more likely because of that intake leak you were referring to, IMO.

Usually headers/exhaust make our cars run richer. A wideband O2 and an AFC/UTEC would be in order here to correct AFRs. UTEC will let you do timing control and CVTC maps as well as rev limiter, yada yada yada...AFC2 will just do fuel.

Nice numbers! 254 is a lot...I guess you need it, hauling that yacht around though haha kidding.

Almost forgot about this thread...

TY for the input! Yeah, I still haven't gotten her looked at re: the intake leak. I know it's leaking somewhere. I can hear it. My bet is the NWP spacers. I'm quite sure the headers are still on nice and tight.

Really been thinking of the UTEC. Have to find a shop around here that knows how to tune with that. Any wideband o2 you would recommend?

[MoncefA33]

I've heard really good things about the Innovate LC-1. You can have one for around $180 on eBay, brand new in the box.

I use an AEM wideband and it works fine for me, decent response and accuracy. Display is easy to read even at night/direct sunlight.

Check this thread for more information -> WBO2 comparison

Make sure you check post #19 if you are considering a UTEC.

utec does not control cvtc maps

Whoops, my bad.
