lq4 partial dyno results
ok so im kinda dissapointed with my horsepower numbers,
lq4 shortblock
patrick g cam 227/235 621/614 110+4
853's
full bolt on
42# inj
so i went to get my car dyno tuned and here is what happened, they said the o2 sensors were bad so they couldnt give a full tune at idle? then after awhile of tuning he said that my throttle cable bracket wasnt right and i was only getting 82% throttle. anyways i put down 315rwhp thru an a4 with 4k stall. but the good news is that it put down 460 ft lbs of torque. i think once i get the o2's fixed, i already fixed the cable i will see a better horsepower #

ls1 throttle positions rarley read 100%. Your car is fine. Most ive seen read somewhere in the 80s.
your o2 sensors being funky at idle is normal, they work off heat. I would have turned them off and tuned the AF via wideband and not by the stock o2 sensors. Then turn them back on so AF doesent change in different weather conditions.

he had a wideband, but he tunes with efi live i think it was and he said he could do tuning in midrange and WOT but without the o2's something wouldnt work right. also this is a reflash of my computer dont know if that makes a difference
