ain't that some ish. oh well. so much for that helping the wallet lighten up some! at least it didn't go down and at least the power is back to it unlike before

 

Drive it for a while, let the computer relearn the engine.

Did you replace O2 sensors? Do anything with the cat?

 

yeah this was my first tank. replaced front o2 and cat was gutted a month ago and replaced with jegs y-pipe

 

Ah, cool. Did you do that before the plenum? Was your cat really bad? Did you notice any power increase? Do frogs have spots?

 

yeah the y-pipe was replaced a month or more and the plenum was just finished a week ago. i did notice more power after the plenum/tune-up. and yes some frogs do have spots.

funny thing though is before i put the new o2 in (post plenum) i took it for a drive and it was uber powerful. not so much now. but a lot better then before!

 

Your not going by the OH console are you ? And did you get the NTK o2 ? Just curious.

 

nah i don't have a fancy schmancy console to tell me that stuff! just a good old calculator

and yeah ntk o2

 

Hmmm. Is that 11 around town or highway? Or a mix?

 

just around town. to and fro work 5 days and a random trip around town on the weekends

 

11 is ok around town, does suck you didn't get at least a small increase though. Maybe you just need to keep your foot out of now, with all that new found power.
