Ive got an 03 chevy silverado ext cab z71. bought it used and have added the K&N cold air filter, the 8 mm plug wire's, the 0ne inch spacer behind the throttle body, the magna flow cat back dual exhaust and the granatelli mass air flow. All have added power and little gas mialege. Now ive got an engine code that says im throwin fuel to the right bank, that comes and goes. Ive looked at the $400 programers that say they will clear it but do they recalibrate it??? What do i do next thats not gonna cost me another arm and a leg???

yeah, they can recalibrate it, i know diablosport does. as far as $ wise you are about outta options if you wanna stay cheap. maybe a throttle body bypass...

T.B. port/polish, I would watch the maf, aftermarket one caused me lean codes until I went back to the stocker.

thanks thats all i needed to know, i'll spend the bucks on a good one

well the truck thru a code with the stock so either it was a bad maf to start with or i just need to the recalibration so its off to the truck store again. Oh well i do like fast.

so far you've spent quite a bit of money on worthless stuff...
throttle body spacer...good for nothing but a whistle or can be used to tap for nitrous
maf...could've used the however many hundreds of dollars on something else

get a real tune...please don't get a handheld. check out nelson performance or at the very least wait4me tuning...
