Pretty General problem...
.You could possibly be right.... the day before yesterday I reset the PCM to reset the SES.. and last night is when I got the codes scanned and the bad front 02 had already shown up.....
And yes, 106+ MPH is enough to run 12's... with enough hook. My old motor in my 86' 13.00'd me to death with high 102 MPH trap speeds. Now if I could only get the "new" car to leave the line that well.

I've pulled 2 plugs.. one from each side...
They seem to look pretty decent to me :shrug:
I think I might go pick up a new set of plug wires tonight... what fun
The plugs were just put in with the header install...
The car dyno'ed 316 with Lid and Loudmouth,
after adding the LT's and True Duals it gained 17 Peak HP, and 27 Peak Torque, but gained over 20hp under the curve in some places and atleast ten from 2.5k - 6k , and almost 33 torque in others..
Once again, here was the before and after...
I have sense added a ported TB.
the dyno did not have wideband.. I am a little worried that porting my MAF after the dyno has my AF ratio screwed to the point where I am losing a good bit of power...
You have almost the same mods.. what did yours dyno?
I sure hope I'm not dynoing as low as 333! I think you will do better with a fixed o2.

I'd seriously be surprised if you got anything over 340... check around on the dyno's here for our mods...
Make sure they don't have pulleys.. ported TB's... and other little items that really add up.. and also.. my car is untuned.

Remember headers are good for 15-25 hp (25 being on h/c) and true duals are good for 10 over most catbacks.
To do both those mods and only get 15 hp seems like a bit of a gyp! Granted, you got the gains under the curve that both LT's and duals are noted for, but I still think something's missing.
The answer is probably tuning, like you said. Don't be surprised if you gain 20 hp.

also... I am throwing the P1153 code.. FUEL AIR METERING on Bank2 Sensor 1
Anyone know much about this code?
back to you, i think your problem may be in the maft and maft ends. these cars are real picky with those. also, are you ataping or someone watching a predetor while you drive? any k-retard? have you added weight to the car?(stereo or other toys?)
good luck. and keep us updated. to many times people ask ?'s and then never come back with the TRUE answers. with these answers we can all learn more and help out better! (ps. try a catch can also... maybee alot of oil getting in to the cylinders? weakning the charge?)

Nope... weight is pretty much stock besides sub frames being added...
I could possibly borrow a predator or ATAP to see.. I suspect I was getting knock retard from the MAF ends leaning out the fuel mixture too far...
I wanna see your AFR
but honestly, some cars dyno differently than others. 331/340 is not too low for your mods. All you really have is headers, duals, ported TB and a lid.
Some cars dyno more than others. Just look at the lady on here to runs low 11's yet dyno's close to 300rwhp (a lil bit more)
Sounds to me its a driving/track condition error, or maybe that ported MAF was really screwing your times up that day.

This was right after I did the LT's... the mods were Lid, LT's and True Duals.
This was what I did yesterday... after I ported the TB, bypassed it. It hit 13.8 lean on that one run... :-/
Car also pops when coming down in the RPMS... and it has just started....
Forgot to say.. the latest dyno was with stock MAF back in place, also having the car Atap'ed this week...
Atap won't tell me anything except if I really need tuning or not.. and tuning... god its pricey.
