Ok my car isn't getting any smoother after 100+ miles w/new abt chip and giac Tip chip installed yesterday. I did the 3-5min "key-on"TBA after installing. Car still surging under medium to heavy throttle, particularly when it shifts.
Should the boost drop off momentairly for each shift of a Tip?
Check engine lite came on after about 80 miles and now the ABS lite comes on under heavy acceleration in top gears. Any ideas on ABS lite?
I just ordered a VAG, 710N TT Bypass Valves, and ABt TBB. I'll do a VAG TBA and then get the fault code I guess? and then install the new parts?
Does this make sense? TIA

Interesting, ABS and ESP or just ABS light?

To fix, try looking under your hood and slamming on the brakes at the same time.

I got these 2 lights with my ABT H-box - what gives?

just ABS light - and only for 10-15 seconds while accelerating in high gear.
