Post Kenne Bell install problems...

[SCdStangGT]

Possibly fuel related...well it's def. fuel related somehow. I got my Kenne Bell installed perfect a couple weeks ago. 10psi @432rwhp...not bad really.
Anyway, I'm having some sort of fuel starvation issue. I'm now running at a constant 9psi...which is really ODD! And my A/F went from 11.2 to 12.2 and the numbers are constant on the Dyno. Not sure if my Kenne Bell Boost-A-Pump is acting up or something screwed up in my fuel map. But its causing me great annoyance and pain that NO ONE can seem to figure this out.

Any help here would be great!

Have you talked with your tuner and/or installer?

Or did you do all the work yourself?

Fuel is off in the tune. Not sure how the 07 curve works. Fuel pumps are maxed out. Fuel filter could be getting clogged.

What setting is your BAP set at?

I started it myself and got to a point where if I didn't have a lift it was just going to be a pain so I had it professionally installed. Not my first choice but i didn't want it screwed up....heh
I talked with them and they couldn't figure it out...
It seemed to me after taking the suggestion from KB to flash back to factory settings then the KB tune again. They kind of threw their hands up, like that voided their work.

Could be a bad tank of fuel??
I'd get a custom tune from a local tuner. You might gain some hp but usually you get better driveability.

There is a TSB out for problems with fuel pumps on the S197s.

And with that much boost, I highly recommend the GT500 Fuel pump kit. You are more than likely runnning out of fuel pump.

KB says their set up for the 07 is fine with just the BAP and stock GT pump. A few other mustang tuners say the same thing. I for one just don't buy it. EVERYOTHER twinscrew manufacturer says upgrade your pumps. I also don't like the price hack for the GT500 pump kit almost $800 from most places. A price tag I just can't afford right now...as for the tune, I trust KB's tune, the vacuum switch is fine, the boost lines are fine, the bypass/valet switch is fine, the BAP is fine (I think). Its pretty much a plug-n-play set up. No cockpit controller, just a preset resistor in there for "on/off".

Wow that would be a long drive to Dan in Phoenix!
