help please..very rich!! p0103 maf high frequency, any suggestions ok guys i just got me a mailbox tune from a sponsor so i could get the car back on road until procharger build is complete.. problem is its really rich, dies when u put it in gear unless u really work with it to keep it goin.went down the road, or tried and it just kinda studders like it loading up. at full throttle it dont seem bad...
it has already fouled out my plugs and i just installed new ones. i also checked and cleaned my 02 sensors. it runs better but still extremely fat. looks like im burning tires at idol.
any suggestions or think tune is off!!
fuel pressure looks good vaccum is right map seems to be reading correctly..
should of known better than mail box tune..
anyone???????

after some thought after some reading around some info shows that a tune that is in speed density mode a ecm will show a po103 code.. i think my tuner left it in speed density mode by mistake.....now i gotta get ahold of texas speed and see if they did by mistake i hope they did so all my troubles will go away!!!
