wideband question

[1FSTBRD]

alright I do not know much about this but here is the problem. I have 98 t/a ls1 a4 bolt ons ran a shity 13.136 at the track sat and it used an awful lot of gas on the way there and home my buddy hooked it up to a wideband and we made a run in third gear from 3000 rpm to redline he said it dipped to 10.9 but stayed steady at 11.0 he said 13.0 is optimal.know here is my question does 13.0 sound optimal,what is the best way to lean it out and should it hit 12's when it is not running so rich any and all input would be great guys I realy appreciate it.

yeah, check out LS1tech, but most likely you need to get your car thrown up on a dyno and get it tuned! i had my car done at Wheel 2 Wheel once, and it's rather expensive ($595 to be exact) but there's a shop not too far from my house that has a dyno and does tunes for a much better price. it's called CARS (Collins Automotive Repair Services) the guys name is Sean and i think he's registered here but never post's......anyways, Jeff (Detroit muscle) had his car done there and they are pretty good! if you have some money to spend on a tune, Sean will make your car spot on!

yea you are fairly rich there. na 13.0 is good. If you were to have nitrous or another power adder you wouldn't want to be 13.0

A tuning program like hp tuners can have that fixed quickly using that wideband

12.8-13.0 is good for N/A
11.5 or so with a turbo. 11.8-12.0 is common for N20

Sounds like your friend could help you out there and like said you wanna be around 13.0
