my car isnt performing like it should....with all the mods i have (in sig) i beat a cobalt ss/sc by half a car and he only had exhaust and k&n intake

so if i go to the dealer and get the reflash think itll make a difference?

 

If there isn't a problem with the tune, i wouldn't reflash it. If the flash held, and you have a 7k redline you're fine. What could be killing you is heat soaking and or your idc's have to be through the roof. No cooling mods, on a 2.85 = 120% idc's and massive heat like 160 iat2's.

No wonder you can barely beat a stock ss/sc lol.

 

^he's on the s2 pulley

 

2.85" pulley is in his sig...

 

ya but he went back to s2 pully...ummm i'd say custom tune...don't u have 60's in there still? if you do i'd say get a custom tune and at the least get someone with hpt and hook it up just to give it a scan give you an idea of what its doin it might not show a cel but doens' tmean something not there

 

mcluvin, wreck/sell that pos already

 

seriously, its fucked since it went to the shop, somone jizzed in ur fuel rail, **** it up again in a wreck, hit a ditch full of water or just drive normally for a week

 

ya i gotta go with zen on this one...cause seriously dude you got TERRIBLE luck with cobalts..

 

i knw ......but yea i got the s2 pulley on it..i didnt put the 2.85 on it cuz i didnt wanna blow it lol....but i have a wideband in now so when i instal it ill see what my A/F ratio is and that might help me out

 

ur car has been through a lot

 

i wanna get a custom tune...but no one here tune's lsj's......and i would have to go to dallas for a tune....plus my dad dont want me spending more money on the car ...sp projekt...u might beat me

 

Damn man that sucks. How far are you from Dallas?

 

I bet if you dropped the 2.85 pulley and ran the Stage 2 pulley the car would run better. I didn't believe it until I did it with mine. The tune was designed for that pulley and always seem to run MUCH better the the 2.85.

 

i dont wanna push the injectors too far

 

No i meant put the Stage 2 pulley instead of the 2.85 pulley.

 

reading > you

 

your going static with the 2.85 and with the stage 2 tune your running pig rich its bogging your car down....when i was running a 2.8 with the stage 2 tune using my wideband on 3rd gear pulls my afr was between 9.9 -10.3

 

reading > you

 

i HAVE the S2 Pulley on the car right now!!!!!! but the 2.85 ran bout the same

 

actually it didn't. Not trying to be a dick, but there is a HUGE difference between the stage 2 pulley and a 2.85. To the temps, to the idc's, etc. BIG BIG difference.

 

i drive my car...i knw it prolly didnt help in the long run....but on cold nights it did run a little better

 

Im telling you McLovin. You just suck at driving!


No JP, I really wish i knew what to tell you.

 

When your injectors are going static, and when your car is creating sooo much heat it doesn't know what the hell is going on, it really isn't running better.

MAYBE on a colder night you would feel a difference because of the heat not being as bad. But do a few back to back pulls and you would know the difference REAL quick.

The idc's and temps on a 2.85 were NOT ment for the stage 2 tune.

 

my car is a mystery....i changed all the plugs to one step colder...doesnt knock anymore up top

yea i forgot to say colder night on the first post

 

Not trying to be a dick but can you explain to m ehow my car with a 2.79 on stg II tune could walk a stage II SS? From a dig, from a roll it didnt matter.



We both had the same supporting mods other than the 2.79 and my colder plugs at that time.
