i currently have 440s installed on my vortech with utec set up however they are not big enough...im getting my car retuned on thursday at sgp in houston...my question is...

will the stock ecu be able to compensate enough for the 525s enough for me to make it from dallas to houston if i take it very easy on the way?

i dont want to pay for them to install the injectors when its a rather easy install

 

no tuners have an answer?

 

You should not have a problem as it will run a little rich but you will be ok.

 

You should be ok, but try to keep your car out of boost. It's gonna be running pig rich!!

 

Drive slow, if you have a boost gauge, just try not to go boost happy. Alot of smoke will come out the back and your engine will bog and hesitate bad

 

Just a thought, you can try adjusting the Utec Temp Compensation to subract fuel until you get a full tune.

 

why dont you just adjust the 0% column

 

Mark at SGP does a great job tuning. He has mine tuned at 415HP. Was just there this past Friday. Listen to what he says. I don't know if you have yet but upgrading to the Walbro fuel pump is something to consider.

I had a return fuel system installed while I was there, Utech, along with the Walbro, and larger injectors.

 

i would try and do some tuning adjustments but i cant even get the utec connected to the comp haha

 

It is not like a big jump from 440 to 550 so I think you'll be fine without hitting boost boost or just rescale the 0 column a little bit more. If you hit boost then maybe you can making adjustment to the Temp Compensation might do the trick until you get you to the tuner...

 

would it b better to drive without the COG belt on?

 

or off so i dont get any boost

 

thats not the problem... the problem would be when you are at idle or in vacuum. You dont want an overly rich condition that could foul out plugs or even worse damage bearings from the oil being contaminated

what problems are you having connecting to the UTEC?

 

see if he will send you a limp mode map...........
