The other night I was out playing around and I noticed about 2700 or so my truck just falls on its face. I had smarty on 8 and TST on 9. It shudders real bad even at W.O.T ? It wouldn't be DEfueling would it? And another thing I noticed is sometimes with TST off it feels like it shudders at W.O.T and won't even spool up. I'm thnkin this pump is ready to take a crap, but it's not throwing any codes at the moment.

 

Look at the easy/simple first.

Have you changed your fuel filter lately? I think during the winter fuel has more additives, if not we add more so it won't gel that cleans the crap from the tank. I have changed my fuel filter twice this winter, both times the truck wasn't running quit right before the filter change.

Just a thought...so you can stop worrying about buying a VP for a few seconds at least.

 

what software is in the smarty? I had power issues and someother issues, and the old smarty software was the culprit

 

If it's the regular TST then it starts to defuel at 2700rpm like the factory and I don't think the smarty alone can carry it on to 3200rpm. Have you checked for codes yet?

 

you should be running a timing program with the tst box

 

It is a regular TST pm3, would the comp take it on up to more RPM before defueling?? I have Edge EZ which is timming and Smarty on #8

 

i would try ditching the ez. Your pump is maxed out for sure

 

that combo only dynoed 405?

 

if I ditch the EZ should I run the smarty on #9? for timing Yea with my little aurora 2,000 and a little smaller injectors that's all it dynoed. I was a little disapointed

 

yes for sure

 

I just checked my codes and i had p0602 which is fuel calabration error whatevr that means??? and the usuall 1693

 

P0602 is just a nuisance code. no sweat
