A must have!
PART NUMBER: 61-1973
DESCRIPTION
Product Information
GFB DV+ Diverter Valve is a direct replacement for the factory valve (Patent Pending). Keep what works and replace what doesn t! By retaining the factory ECU control and recirculating the vented air, the DV+ is a purely performance-oriented product that offers the following benefits:
Sharper throttle response
Faster boost recovery on gearshift
Solves boost leaking issues
Built to last
This Direct fit replacement for the factory diverter valve uses the existing solenoid with TMS advantage.
Works with stock hardware, improves performance and reliability. Exclusive pilot activation system allows HIGHER boost pressure. The end result is sharper throttle response, lightning-fast valve actuation, and the ability to hold as much boost as you can throw at it.
The OE solenoid itself is great- the ECU opens it faster than any pneumatic valve so why replace it? The only valve on the market to solve the problem without flutter, excessive cabling and extra parts, installed in half the time at more than half the price.
WHEN you want no noise, no nonsense, just performance.
European manufacturers are pushing their engines to the limit. Get a DV+ to match.
GFB s DV+ diverter valve range offers a direct-fit performance solution for the weak factory diverter valves used on many modern vehicles.
Retains the factory solenoid coil for seamless integration Replaces plastic valve parts with metal for reliability and strength on chipped engines Direct-fit replacement with GFB s TMS benefits Exclusive pilot-actuated valve mechanism for rapid response at high boost
GFB expands the DV+ range with a direct-fit solution for the weak factory diverter valve used on many European vehicles. The solenoid coil itself from the factory-fitted valve is great (the ECU opens it faster than any pneumatic valve so why replace it?), but the weak point however is the valve mechanism itself. So GFB s DV+ solves this problem by replacing just the valve parts with an anodized billet aluminum housing fitted with a brass piston machined to exact tolerances.
The end result is sharper throttle response and lightning-fast valve actuation, and it will hold as much boost as you can throw at it. Read all about the DV+ story on the next page.
Other manufacturers products involve replacing the entire system with a traditional pneumatic valve, requiring long vacuum hose runs, additional parts for tapping into the intake manifold vacuum, plus either a different solenoid valve to actuate the pneumatic valve or a ballast resistor to plug into the OE wiring loom. All these additional items result in a product that is slower, less responsive, more expensive and takes much longer to install.
Sean's Installation Notes:
Do not pass go until you have purchased a GFB Diverter Valve. This is one of the best upgrades for the 1.4 engine turbo engine, even if it is bone stock. Boost is more consistent, throttle response is sharper and the operation of the valve is silent. Installation is very easy and takes less than an hour.
BRIAN'S APPLICATION NOTES: YES, this is in our Fiat 124 because we noticed even the first day of driving that the boost delivery was lumpy and inconsistent...which this item fixes. The stock valve is leaking all the time, by inconsistent amounts. If you want the boost delivery smooth and reliable, this is your first mod!NOT CARB APPROVED, CANNOT SHIP TO RESIDENTS OF CALIFORNIA.

Go Fast Bits DV+ Diverter Valve
Straight forward install - 20 Minutes. Car runs better than before.
I bought the GFB DV+, it took about 15 minutes to install, took it for a spirited ride, and you can tell the difference. The turbo is much smoother and keeps its boost
My record Monza is a big fan of it. It just keeps popping every time I shift gears.
Absolute music
I'm very pleased with the change in performance. It eliminated that hesitation when you step on the gas. Very easy to install. Great instructions in the box and I watched a YouTube video. A very smart buy!
Easy 10 minute install. This should be the first purchase for any FIAT Spider owner. Very noticeable when starting out in 1st gear.
Installed this in about 20 minutes. Noticed an immediate difference in the smoothness in acceleration when running through the gears! Makes the car even more fun to drive !! Did not think it would be that noticeable. Thanks, I love it!
Hi Brian, I finally out the GFB diverter valve in my 2018 Fiat Spider. It didn't take long to install. I noticed the difference just by backing out of my garage bay.I didn't have to increase the RPM as much. Off the line in first gear is great! No more increasing the RPM to prevent a stall. In the low gears, the turbo lag is virtually gone. Great Product. Next week the complete exhaust,resonated with quad tip.
Easy install. Almost completely removed issue of turbo lag. Definitely not on or off like the factory part. So smooth. Makes changing gears less dramatic. No issues with check engine light. Very satisfied.
I just received my diverter valve upgrade from good-win today. it was probably one of the easiest things I have done to a car.
the performance overall seems to be the same, but where this thing is great is when you are tooling around moving slow in stop and go traffic. it seems like you are on boost at considerably lower rpm's.
I have stalled my car a few times before the replacement in traffic. it seemed like the engine was not generating any power below 1500 rpm, causing a stall. if not stalling it was a bit jerky in transition from idle to low rpm crawling. the installation of the d/v seems to have cured this condition, also when shifting the transition is also much smoother.
I know learning a new clutch is sometimes getting to know the feel of a new car, but having driven manuals for 33 years now I have a decent level of mastery of a manual cog swapper.
this d/v based on ease of installation and noted improvement in operation is a must have.....
Install was pretty easy although original part damaged - too fragile to get out with anything I had.
Turbo performance is better with this part, although it did not eliminate all the "lumpiness" as Brian calls it - probably 50% better. This is the first upgrade on my new 124. Perhaps new crossover/midpipe/exhaust will get rid of the rest?
Hi Brian, the GFB diverter valve I put on my 2017 Fiat 128 Abarth has really given the car a nice smooth boost since I installed it. Installation was actually very easy and I did use the spring and have not gotten any bad codes and have driven the car a bit hard a couple of times and I did pull away from a couple of porches for a stretch but of course they caught up with their extra horse power, mine just came on a bit quicker than theirs and it really pushed us into the seat when we hit 25000 RPM-3000 RPM. Just like my old Mazdaspeed. waiting for the intake to come available.
Great product. Does take some time to install but worth it. I would have given this 5 stars but would suggest a tool be included to remove the plastic ring for the factory unit so not to damage this piece.
