Well, for starters; its got a 93 NON-ALKY chip, burned for 15-17psi with appropriate fuel/timing for that boost. Alky chips do have higher base timing as Ive read.

Jim, I know its a TT 5.6 chip. For stock everything. I thinks it 20° 1st/2nd & 18° 3rd/4th. Not sure. Ive got new injectors so a new chip is needed.

ive run 27/24 timing in the 87 (all i could get from that chip) and usually run 26/25 in the 86, but for you start at 23/20 , tune with fuel for no knock as you increase boost, dont be bound to a number on SM for o2 as those suck but for you Id suggest 800s atleast , best way to tune is AFR and watch egt , then once you reach your target boost if desired you can lean it out using highest mph as your optimum setting and watching egt , then after all that if desired start adding timing keeping a very careful watch for knock at shifts and for any creeping up through the gears all the while your tuning (get a logger before playing with timing)

Im not gonna mess with nothing untill the car is mechanically ready and I have a logger of some sort. I just sold my TL on TB.Kom.
