well at least you wont have to hollow out your cats and you'll gain a a good 10 or 20 hp from that.
Just tell you tuner to delete the rear 02's and leave it set to pass emissions.
congrats on the extra ponies, it'll all work out

tried all
i calibrated the lm-1 in air,started up ok and then got worse as it warmed up.3.3 lamda.center pipe off at intercooler had the same thing.the stange thing is the left bank seems to be the problem.the right side does not backfire and has the normal water at the exhaust pipe.mike

can you explain that a little better? So others can understand what you did and not make the same mistake?
Are you saying the driver's side coil harness was upside down, so 8 was going to 1 and 1 was going to 8?

Heck, that doesn't even make any sense. The evens and odds are on different harnesses and opposite sides of the motor, so I don't know what the heck he is saying. Maybe a connection somewhere else was flipped or reversed.

not much of a wrighter
when my friend took the coil pack off, to cut clearance for the fuel line. he put the #1/8 yellow tag on #8 instead of 1 of 8.it was like wiring a distributor cap wrong but real hard to see.hope that clears it up.i am still not ruining right yet.the cooling sys. has been a bitch.i burned up no. 2 wire today,too close to header..tomarrow is my fifth try at the cooling.mike in mobile.
