Not sure if you figured out the P2261 issue but this is typically the aftermarket bpv spring is heavier than stock and will throw the code. You have two options. Your tuner can tune for the heavier spring or you can buy a new spring with stock pressure.

With all the mods I have I figured it was time for a coil upgrade. I decided on the MSD hoping performance for value would be good. With little to no reviews or stock coil specifications I wanted to test the coil within what I have available. I know not the best test and not conclusive but...

Anyone else experiencing this? Been working on dialing in the throttle % with BNR tune and medium level throttle input while in boost I'm getting a very hard blow off from the diverter valve while still on the throttle but just backed off a bit. Doesn't happen at WOT just during medium...

If you have seen Mamba now sells their wastegate for the cruze and sonic. Kit comes with six springs and their yellow worked best with the BNR tune. Also this wastegate fixed the issue of the stock wastegate with the BNR tune being quite a bit of part throttle boost which isn't enjoyable for...

Mamba wastegate actuator now available Hello guys, I've been working with a contact at Mamba for sizing and they now have a wastegate kit that will fit the sonic and cruze. It's a nice wastegate for the price with different spring rates. Easy to install and adjust. I'm still playing with the...

Update 11/3/18 Results: Individual mod test 0-60, 1/8th mile time with data log Update 11/3/18 I've added the Momba wastegate and tested and now have the right spring with right preload. This last mod with BNR tune, midpipe back zzp exhaust and GM performance intake 93 octane now best 0-60 is...

I've searched everywhere and can't seem to find an answer. Anyone know the stick wastegate spring pressure/bar/psi? Anyone know the Bnr wastegate psi for comparisons?

Grabbed obdlink and torque pro app and tested boost and afr at WOT. Does below seem right for tune with supporting mods or intake and exhaust? I've been reading if people holding close to 20psi toward Redline but I have no base to compare if this is correct or I may have a leak? WOT 1st gear...

I'm just curious if anyone here would find what I tested interesting or not. I purchased a Dragy for testing 0-60 and 1/8 and 1/4 mile times for my vehicles. I was really curious of how much time each mod gained 0-60 ect. So I installed mods and tested individually and together on the same day...

Anyone parting their car that has one for sale hit me up.

So I received my initial tune right away and I provided my data log on May 10th. It's been 3 weeks and I have yet to hear any follow up. I've since acquired the 42 LB injectors for an E85 tune. I understand they are backed up but is three weeks typical with no response? I've also since followed...

Comparison: Opt7 5000k 55w bulb vs Morimoto 5500k bulb both bulbs using the Opt7 55w ballast. I've had HID's in all my vehicles for over 10 years and my last car had factory LED's so it's easy to say I need good lighting. When I picked up my 2017 Sonic the headlight output was pretty bad...

Just curious. I see that the 2017 cruze is rated at 153hp / 177tq compared to sonic 138 hp / 148tq which I understand that there are a lot of variables for the difference. I see that the part numbers are different and seems it may be a direct bolt on. Just wondering if a 2017 cruze turbo is a...

Will any current model EFI live Autocal work to upload a bnr tune? Got a friend selling his and may pick it up if it'll works. Thanks in advance.

I picked up a 2017 Sonic fully loaded late last year and one of the first things I did was upgrade the lights as I wasn't happy with the sock halogens. I didn't want to post right away as I wanted to drive with them for some time before I gave my feedback. I've had them on for about 6 months...
