Exhaust Gas Temperatures - VW 2000 GTI 1.8T
GIAC 1.2 BAR Chip. Full run on the freeway (note RPM's)
3" DP + race section results in a peak of about 250 degrees less, peak
3" DP + 3" cat section results in a peak of about 200 less off the chart, peak
I don't have charts with the 3" dp + cat, but I do have the data. You can recreate this information using a VAG-COM tool.
