DSX, Fore Innovation, Squash dual pump setup? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Can anyone tell me the pros and cons of each of these? I am looking to run E85 and be around 700whp. Prices seem to be similar but I am wondering if the in take options might be better? Which would be easier to install?

DSX allows you to retain stock PCM control of fuel pressure via PWM and the FPCM. A problem unique to the ZL1's, CTS-V's and ZR1's. Dave can step in with details on that.

My system keeps all the functions of the factory FPCM in place and allows for live pressure reporting. The install is also a lot faster, and all of it is plug and play. The only downside is tapping the gas tank.

I don't think the price is comparable at all really though. My system is only $1000 which includes everything (minus the drill and tap), and I offer free FPCM editing if you send it to me in order to allow a ton of pressure. 700whp will be a breeze for it. PTFE lines are standard in mine.

I'd suggest ordering it with the drill and tap to make sure you have the right tools for accessing the tank.

The system is here.

Love my DSX setup, Aux Pump and Flex Fuel Kit, Dave did the tuning on the FPCM and tuned the car, i was providing logs with Lambda AFR.

Car runs great, hauls major ass...

I recommend 1050x injectors, i am around 73% DC with 80% Ethanol Content at 6500rpm

Even better i can send you the drill bit and tap to use... save you lil coin

Dave's system is not only 1/2 the cost, but it does almost exactly what the Squash and Fore systems do without all the extra plumbing, but in a better way. There are no new fuel feed or return lines to run to the fuel rail, no regulators to install and it allows the PCM to dictate the proper Fuel pressure for just cruising around town and make its own adjustments when under boost and more fuel is needed. The Fore and Squash systems use a mechanical regulator and are fixed pressure no matter what the boost pressure is. Ultimately all three systems do the same thing which is activate a secondary pump when boost pressure is detected and I really didn't see the point with replacing the stock FP with something that in a way is inferior since you have to disable the FPCM.. I have been racing on the DSX system for a year and a half now 300+ passes and never a hiccup, and the car runs 100% stock around town. I don't think i have read a single complaint and Dave has a lot of systems out there now. AND most importantly, Dave is VERY accessible on Facebook (DSX Tuning) if you have any questions or problems and very knowledgeable about LSA and GM platforms in general!

To sum it up, I am a very satisfied customer.

DSX, no question:

My install and dyno, excellent kit, fairly simple, and just works:

DSX is the best flex fuel setup.

I've seen people have problems with Fore.

2NASSTY · 07-14-2017, 06:42 AM

I agree with everything said above. I will be installing DSteck's system next week after a ton of research on the best LSA fuel upgrade.

I've been following Dave Steck since he innovated his Flex Fuel sensor years ago. Tremendous resource and tuning knowledge. There are other Vendors out there selling his systems so it can get confusing. Buyer beware

bct10985 · 07-15-2017, 10:31 AM

How much power will the dsx setup support?

DSX Tuning · 07-15-2017, 11:32 AM

1000whp on E85.

Devcon 7 · 01-09-2018, 06:18 PM

Is there any potential longevity issues while running corn with the dsx kit?

Been running it for 2 years now, lots of drag strip time...0 issues. I run on 70ish for most of the year. the only thing I don't do is store the car over the winter with E in the tank.
