the next thing we're checking is the injectors, but what are the odds of them both going out? they are brand new, maybe 1 month old greddy 440cc.. got em in when i got my tune done.

 

What i heard bad injectors can fail in short term.. That's one of reason i bought mine from IP when i got my first tuned. But is there way to check injectors are still good? what i heard was you have to send it back to company to test it out.

Do you have RFS?

 

return fuel? I dont think so... i'll ask the peeps who did my install... they shouldnt have been bad injectors, esp since i bought em from the greddy kit.. brand new in packaging... what are the odds of both going bad?

 

Is it possible my Utec did something?

 

Why you asking this question?

It is possible.

 

someone on g35driver recommended it.. i'll try it when i get home on fri

 

How about taking it back to the tuner and seeing what he thinks? In theory he can troubleshoot a potential utec issue quicker.

 

Check out Map sensor.

 

tried the utec thing.. no luck.

 

Take it back to the tuner and see what he thinks.

 

Chris is just a tuner, he is not running a shop. He do tune the car by appoitment and teach class. He did also tuned my car, great tuner wish he does have a shop.

 

I'm now lost, could you tell us what have u been done and more details on your car now.

Is it running? Or...

 

wow, i'm having a similar problem.

DW 440's
vortech
SS box
headers, testpipes, borla duals

slightly rough idle, low power, a/f looks good (a little rich actually). i'm lost too. new plugs and new injectors.

I'm getting 10lbs of boost so i don't have a leak.

 

Do you have RFS? if not it might possible could be that or Tune.

 

I do'nt have a RFS.

Tim on here is helping me tune. He knows his crap and just can't get this to go away so i'm thinking it has to be something else besides the tune.
