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

BigBlue

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?

Bob Wagner

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

Bob Wagner

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

Bob Wagner

that combo only dynoed 405?

rollinsmoke

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

Bob Wagner

yes for sure

rollinsmoke

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

Bob Wagner

P0602 is just a nuisance code. no sweat
