New Jubu Emira update 435 hp

LOL - I went to the website link and all I learned is it comes in a box

I'm assuming this is a piggy-back solution as I wouldn't expect the ECU to be cracked so soon?

pretty cool, tho idk if im ready for the headache that comes with adding a tune again. my current car has a tune and there has been some scary moments, tho nothing catastrophic yet

Yeah, as much as I want to immediately go for ~450bhp I'll wait until it's out of warranty. That 3rd cat delete + Milltek valve controller will happen immediately, however

oh 100% those mods sound incredible. worth every penny. I like the idea of having the valves open while also having traction control on. ill probably do the catback exhaust upgrade as well.

Must be a piggyback or I figured they'd have raised the rev limiter.

434 hp calculated with an unknown drivetrain loss assumption and smoothing set to 5.

That is an odd-looking dyno. The torque curve doesn't have the same general shape as other M139 dynos, especially with the flatness of the top-end output. Bottom end torque curve depends on a variety of factors, so the shape there isn't as indicative of issues. It would have been good to see the stock dyno for comparison.

I suspect that a version of this is involved......

Probably because it's a V6.

I highly doubt that, what you linked is a complete ECU replacement.

I'm most likely wrong about the piggyback and it's just an ECU remapping as it is here https://www.jubu-performance.com/en/shop/part-jubu_exige__evora_430-1839

Did they post a baseline prior to mods?

That's just, like, your opinion, man.

I don't know why I thought it was an I4.

"Modified Software-Stack for OEM ECU" says piggyback to me. Also, with this modest upgrade, it's a bit meaningless without a baseline dyno.

EZcheezy · Aug 15, 2023

oh this tune/service also includes changing out the air filter and downpipe?

Ecu flash (supposedly not piggyback), air filter intake, third cat delete and installation.

pretty good price for all of those things included

theres some caveats as to why, but i paid way more for the equivalent on current car

It looks like suspension and wheels make quite a bit more difference than the 435 tune does.

Not even remotely surprised, you need a _lot_ of horsepower to see large track time changes.
