In that particular case, the 3rd cat delete with a milltek valve I think was the only mods done to his car and the dynojet sheet showed a +13 WHP.

Myself I saw a before & after dyno onto Lotus Emira Owner USA facebook page.

With the Jubu 460 kit, the SC pulley is even bigger to get less boost, lower engine bay temperature and putting less stress onto the engine. So that means without doing that it would be called a 475-480 kit in fact. Remember the JB4 test car had a GRP 3rd cat delete, It is a 13 whp right there...

Yours was pushing toward outside like the others I guess or pushing toward the inside like mine creating a bump ?

Does anybody knows how to adjust the rear bumper. I have a bad fitment on the passenger right side. ( see the pictures below ) The driver side is perfect. I removed the fender to have an acces to see how it was done behind but I do not understand what I need to do to release some pressure over...

I own a lotus since 2007, I bought parts from Greg for more then a decade for several several thousand dollars and never been worried what so ever but this is not the point here. The point is that Burger seem to fullfill people ordering from them directly faster probably because it is more...

Fingers crossed 🤞the second batch is starting to ship. Let the fun begin.

Wow you find the part fast. That is good news. Where did you find it and for 1200$-1300$us I guess ?

Same boat here. It could have been faster to place the order thru burger website. I think they may give the priority to those placing order directly from them. We saw someone here who placed his order after us and got it at the beginning of last week already. It shows how people was...

I did not realize the Lotus lettering was a sticker onto the caliper. I tought the lettering was painted.

I had a crazy thinking about having my silver brake caliper painted to match with the yellow wheel center cap but I was not sure enough if the paint job quality result was going to be as good as oem and also to keep the Lotus lettering on it. Who did your and how much they asked ? They look...

For sure I will. My order has been placed on may 7th. Greg from GRP should ship mine tomorrow so I could get it by this friday or next monday june 2th. My review is going to be around june 5-6th.

Well your affirmation is partially true in regard to the map1 on 91 octane gas. The torque is a bit better at lower RPM like kitkat said but the major gain is between 5K and 6.8K. So the map1 is going to feel similar for cruising around but at wide open throttle the difference should be...

My JB4 is suppose to be ship next tuesday and I’m ready to pass the OBD2 cable from the cabin to the engine bay as soon as I get it. I did not have to remove the wheel and the inside fender. I used an electrical cable and I will use it to pass the JB4 cable thru. The wait is almost over.

It look like the main harness is passing thru. I tought the hole was empty and not used.

Who dont have a cell phone these days ? Especially if someone is into / looking for tuning and dont already own a laptop or a cell phone it would be pretty surprising.

We cannot do proper data log without the obd2 cable connected ?

Time will tell if others with map2 try a 0-60 acceleration time.

Bell and Colvill ask 899 british pound = 1 215$US.

The piggyback is a 10-15 minutes job to install / uninstall for the V6. ( 4 electrical connectors to unplug then 2 connectors to replug. ) Easy like 1-2-3 located on top of the engine bay. If you do not make any hole into the firewall to pass the OBD2 cable, my guess is there is no evidence...

This car blew the engine with a Jubu 460 kit. The car has been sent to Jubu in Austria and they did the replacement at their own fees. I know this car has been tracked pretty seriously so that means if you raise the power and beat the crap out of it wont last long. We all know the Toyota...

Order # 23 480 present 🥵 it was borderline. 🫡 😃 Note to myself : Do not ever launch the car on map2 . 🪦💀😱

He got +or- 20 last week and he’s hoping to get another 10-20 this week as a second batch. Burger are making those kit by hand one by one. That’s what he wrote on YouTube into the comments below the video.

Same here. He must have placed his order directly from burger 🍔 instead of GRP. Better thing come to those who wait they said.

Mine is going to be mounted with zip tie temporary if it arrive before the mount I can tell you !

That is exactly what I was doing with my Exige running the BOE Torque300 tune and my FT86 with an Ecutek tune and it works just fine but not every octane booster are good. If you buy those who are cheap it wont work. You gotta pay to play. :)

Your milltek valve broke ? So you had to remove it ? Do you know if it broke because the first version was exposed to water ? No warranty claim possible ?

One day ! one day my friend .... LOL +13HP with the milltek valve fully open ; Interesting. Do the V6 JB4 test car had the milltek valve controller installed ?

Similar result to JB4 map1 : With 3rd cat delete.

Coming from an Exige S300 with a power to weight ratio of 6,66lbs / hp , the Emira needed more punch for me since the beginning. At 480 crank hp on map2 I should get that exact same power to weight ratio so I should finally feel back home. +80-90HP is a very considerable gain and it should be...

Greg think that Jubu are very conservative about the max torque limit the transmission can handle. They may have an interest to present thing that way to sell more parts. If you drive your car into the streets and do not beat the crap out of it for drag race or at the track on a regular basis I...

There must be a way to route that cable into the engine bay without having to drill a new hole by using an already existing one… I wont do that extra hole for sure.. If I route the OBDII cable temporary by the driver’s window thru the engine bay and drive the car a couple times like that to...
