i dyno my car couple months ago....made 405 RWHP...dyno today....367!!! wtf is going on....my car dies alot i think the timing or the tuning is really messed up..tell me what you think i need help bad!!!!!!!!!!

 

it can be tuning but it wont give you 40hp


the ses light thats on in your car could be the problem
eventhough i think its the code for 02 sensors it can cause some loss


...or your horseys decided to make a run for it...

 

yeah i talked to venomousracer and he said to get a custom comp chip made..it should add 35-45 hp in my case..and take care of those problems.

 

It's actually the "law of depreciation" that the 00 SSs expierenced, after a while the 00s begin to lose power. Seriously though your AF wasn't that far off you might be able to pick up 10-12 if you get that dialed in and I'm sure there's some more in the timing. Take those cats off to, who knows maybe there clogged up or something. That power had to go somewhere, come to think of it defiently check the cats, maybe thats why your exhaust is stinking so much.

 

its those damned 2000 black ss's....

u defintly need a tune and then see what u get

 

Thank God my Black SS is a 2001

 

lol..



ok now seriously anyone know the problem??????

 

stupid f-bodies.....

lol jk!!!!!!!!!!!!!!!!!

 

lol ya.....


OK LETS GET BACK ON TRACK....

 

yeah please someone help me out....this totally sucks

 

You mean a bad 02 sensor can cause a decrease in hp? WTF?

 

yea im preety sure...cuz it determines how much fuel gets dumped in....it isnt a huge amount maybe like 5hp

 

depends. if its the rear 02 then your car will retard the timing. if it was that though you'd definately notice right away. has the car been tuned in the past? was it tuned on a wideband? if its untuned it is possible you've got some plug issues or fouled cats (if you still have those). if your untuned your probally running very rich, so everything that could get fouled is going to get fouled alot quicker. what did your dyno sheet look like? was it all erratic?

 

his car has been tuned......

but heres a question....

if you unplug the battery for a long time will the tuning get reset back to stock????

or is it remembered someway else?????

 

It is the one behind the right cat. I had probs with those. Which is why I got em replaced to high flow cats. My SES light is on, autozone says its the rear right 02 sensor behind the cat. By retard timing you mean that if I gun it off of about a 30 mph roll, it will not pass up 3500 rpm. Cause every couple of weeks or so when I gun it at about 30 mph it wont rev past 3500.
