To Lambda Or Not To Lambda
 

Ok you tuners, I need your help. I have power fc, single turbo
and the other goodies and am doing a street port and 3mm
seals. I was told I need to remap for more fuel etc. Do I
need to remap? Also I was told the only way to be sure is
to tune with a wide band lambda on the dyno. They say the
stock sensor is not accurate enough. I have an egt guage
and the fc gives o2 voltage so why the f--k do I have to
drop 1300 smacks on a lambda. Nobody has one around
here.I can go to RP and let Ari do it but Dallas is 6hrs away.
Don't get me wrong, I'd drive to hong kong if I had to.
By the way, my voltage stayed around .90-.93. I really do
appreciate you guys- peace.

You'll need to remap fuel to compensate for added hp with that single turbo. Street port and 3mm seals will let you abuse the car a bit. You'll need to upgrade fuel pump and injectors to get that new fuel to the car.

Wide band O2 is needed to tune the PFC correctly on a dyno. Driving six hours to have Ari tune your car would be worth it.

Thanks, already got 1300cc secondaries and fuel pump I called
Chris at RP and will head over there after break in. I appreciate
the info....
