Hello,

I currently have a Stillen supercharger, 600cc injectors, utec engine manager. I have to go back to stock but I have few questions:

1- Can I simply remove the UTEC to go back stock or the OEM mapping are no more into the ECU?

2- Can I keep the upgraded fuel pump if I put back the stock injectors and run the OEM ECU or it will be too rich?

Thanks for your help guys.

 

Sell me your stillen kit. PM me with price and details.

 

OP,
try to PM "Djamps".. that guy is a freak w tuning.. im almost certian he'd know exactly.

 

Thanks Bmccann101, I will send him a PM.

 

Pm'ed him but no answer... Anyone else can help? I don'T want to change the pump if not absolutely required.

BTW, the pump is a walbro 255.

Thanks guys

 

You can just unplug the utec but will have to change the injectors back to stock or it will run pig rich.I would think you could keep the fuel pump.

 

The Keith has spoken!!

 

I was running the stock injectors with 255 walbro for a while without issues.. but then swapped the injectors to 550cc same fuel pump and I was running way too rich.. until I took it to get reflash.

 

Thank you guys, I have the answer I wanted (not forced to change the pump is a good news).

I will go with stock injectors.

 

Are you selling the Stillen?

 

Yes, I will sell my stillen supercharger, the Utec with map selector, the 600cc injectors, my HKS twin power. And the Stillen hood to clear the unit.

I will post localy first (prefer not to ship)...

But NY is not so far... I am 1h East from Montreal, or about 1h North of Newport...

 

Why are you gusy so worried about pumps? Its like a 15 minute job.

 

Few reasons,

1st, I never done this job before so have no idea if a pain in the *** or easy job
2nd, I no more have the stock pump and the assembly have been modified for the walbro
3rd, the car is stored for winter and full of fuel

It is not really good reasons, but for me, it'S a show stopper.

ive got stock injectors for $125 shipped.. want em

 

Lulz...please post a video of you swapping in a walbro in 15 min.

 

Its not swapping in a Walbro..its swapping one out with an OEM. Try to keep up.

That wouldnt involve any modification. Unscrew 6 screws. Pull housing. Pop off bracket. Swap pumps. Put back in and screw 6 screws back in.

10 mins i bet.

I replaced one on the interstate in that amount of time. Turned out not to be the pump but a blown fuse.....just sayin.

If i did take the time to make one and its under ten minutes will you show up at my door step so i can kick you in the nuts? Then it would be worth it.
