2003 Mach 1. Classic bolt ons, sct4 custom tune from reputable tuner. (yes not quite svt but also not 2v)
Bolts ons include: (for tuner purposes)
JLT fenderwell CAI - dry filter
1/2 intake lid spacer
Factory manifolds with o/r Mach prochamber (oh that sound!)
Mac cat back
4.10 gears
305/30/18 rear tires (for speedo correction)
EGR eliminated.
Car sits on eibach sportlines, mm cc plates, koni adjustables, Steeda weight jacker LCA, Team z double adjustable uppers, aluminum driver shaft (with safety loop), factory sub frame still, frpp rear diff w/girdle support, studded rear end mains, 31 spline moser axles, stainless brake lines (have some low profile rears to go on at some point to clear 15x10), slotted/drilled rotors with new pads/calipers etc, mgw short throw, mcloud clutch, etc etc.
Car was recently retuned as my sct3 tunes were lost and the "stock" file I was using simply was gutless. Very reputable shop is doing it remotely (no data logs sent yet). Car pulls AMAZING (my butt dyno likes it at least), but I'm getting slow o2 switching codes popping up at part throttle semi spirited pulls.
Codes:
P0153 Slow response bank 2 sensor 1
P0133 Slow response bank 1 sensor 1
Obviously the rears are turned off in the tune(s), 93 octane tune. Zero pinging and it runs smooth, no misses, no hiccups. Just the damn ses light pops on after a few drive cycles. Can reset it and one of those two codes always comes back.
They've sent me one retune and same issue. I asked if they had the front o2s adjusted for long tubes (which the car does NOT have) and they said no. Other ideas here? Only their tunes kick these codes. My old school canned tunes do not trigger these codes -ever (except one doesn't turn off egr code lol).
