A cat-back with a proper straight-through muffler should add 10-12whp and similar torque gains.

And also how many people have this xflash, and how long has it been out without any issues?

Thanks.
I can't speak for the products from other vendors but our XFlash is perfectly safe, even at 22-23psi. It's a torquey little sucker...

No its the same princilpe Vishnu tales the restrictor pill out works manufactured a hose
To make install as easy as possible (that's one reason someone would chose a flash over the XEDE), we actually include a replacement hose. No need to squeeze out that little pill

If custom tuned, the Stage 1 XFlash will provide the same power as the Stage 1 XEDE/XEDEFlash combo. Just different means to the same end as far as engine control goes.

Shiv,

You say that with your tune, "momentary 22-23psi, quickly reducing to 19psi, where it tapers gradually down to 18psi by fuel cut".

I have the Signature Turbo Back, custom tuned. Subsequently (as a result of factory boost cut), I added an SBC ID electronic boost controler. It appears to hold full boost to redline (21-21.5 psi). How does the SBC ID and the Xede boost control parameters interact? Also, am I at risk holding full boost to redline if I intend to use the car at road course events for up to one hour runs?

Thanks.

Stephen

Hold on Stephen it sounds like you have the xede also? I feel its a bad choice to get rid of the FBC (with RPM dependant boost control) as it would be very expensive $800+ to find an aftermarket equiv. the SBC ID and the Xede boost parameters dont interact you took that out of the loop and the EBC is now controlling the boost independantly of the ecm. Now as far as "How Off" you are from the tune not that far but then agin you still cant control boost in a RPM dependant way (If you road race you want the consistancy)

BTW I did a whole track weekend in texas heat on pump gas monitoring a number of conditions and the Stage 1 Xede was flawless

the pill removal needs to be tuned for. It could cause a spike but we have an RPM dependant FBC. It does allow for a couple psi additional boost.

Ive got 8K on my car with 400 HP to the crank 2 Full track weekends, 3 Autox, 8 drag passes and no slips or signs of wear. I dont see a need to do the clutch thing. Some swear by it

Thanks thats nice- I easily remember things

No thats the Royal Tennenbaums

Shiv,

I dont think Ill be going to Cali soon. I have the same stage 1 set-up with a Walbro 255l and ARP head studs. How much would it cost me and how many HP and TQ do you think will my set-up XFlash for 93 octane?

Thanks.

Hi guys,
XFlash is a bit different when it comes to boost control. With it, we do what we do with the XEDE. That is, we allow for a mild overboost in the midrange, between 4000-5000rpm which improves torque substantially. But at high RPM, we still employ a gradual boost taper like stock, but not as steep. This allows us to run reasonable advance numbers which makes the car consistent, run after run. We've found that trying to hold boost steady to redline makes the car awfully ping prone and inconsistent-- espeically in lower octane conditions like in CO, CA, AZ, WA, etc,. Peak boost, in stock cars, is a momentary 22-23psi, quickly reducing to 19psi, where it tapers gradually down to 18psi by fuel cut. This basically allows us to keep a healthy distance between operation and knock throughout the entire RPM band. I have dyno graphs of a couple of cars we've done in the last week which I will put on-line as soon as our scanner starts working. It illustrates the effects of the revised boost control quite nicely. In all the cars tested (all completely stock Evos), hp rose from 195-197whp to 218-222whp on the baseline map-- no custom tuning. Torque had similarly impressive gains. Consistently. This made me happy

Cheers,
shiv
Shiv,

I have some questions about your Xflash. From reading your post it looks like you can do rpm based boost control with your reflash, is that correct? Also on your website it says there will be a Xflashtuner to adjust boost, timing and fuel. Will this Xflashtuner be like a piggyback or can we actually use it to reflash the ECU by ourself? If you can give more info about the Xflashtuner that would be great thanks.

So, even for the base Xflash, you will still need to remove hoses and change to the ones without the pill? Is this for both the Xflash and the Xede, or just the Xede? My understanding was there were no changes except for the computer reflashing with the Xflash.

Does the Xflash eliminate fuel cut as well? Does anyone know if you have to change the hoses with the Xflash to eliminate the pill, or is this only for the Xede?

yes fuel cut gone. The xede takes the pill out it is my understanding that the xflash might come with a hose

Do you know what it raises the fuel cut to? Also what if we have a good 255 pump what is the MAX boost that is safe? 23-24psi to redline? Right now I lowered the low end 4500 and down from 23 PSI to 20 and it feels better, maybe because the top end pulls harder then the bottome end.
