Attempting to track down what might be a potential issue with my FWD 1.8T with automatic 09G transmission.
Noticed once I installed my JB4 and watching the guages that I'll occasionally have an AFR swing where it will go from 14.5-14.9 swings at steady speed ( so far 35ish to 50 MPH) to jumping up to 15.5-16.0, holding for 3-4 second and then dipping to 13.5 for 3-4 seconds and returning to the 14.5-.9 Which seems to be normal.
Originally saw it on my stage 1 flash, but I've flashed back to stock and still see it, while not as often as with the flash.
Car is currently running stock flash in Map 0. FMIC, catted DP with straight spacer, TIP, intake tube and Afe filter. APR coil and Ruth's gapped to .24 with under 500 miles on them.
Any other 09Gs seen this issue? Attempting to see if its something with the slush box that's normal, or if I have a potential issue somewhere.
Any advice welcome.
