AEB Engine mods

[TomboB5AEB]

Hiya folks, I'm new to the forum and have an AEB B5, it's done 100k and has a 3" exhaust and come filter so far. Was looking in to an ECU on eBay that tuned by CCCTech. Anyone know if they are reputable? Just ordered a vag com lead from eBay and a new MAF as the pins on the previous one' pins fell out when I attempted to clean it with contact cleaner!! Was running a bit weird before that, the power delivery seemed to be random. Sometimes it would rip and other times not so much. I changed out the N75 for one from an AEB I found in a local scrappy and that sorted the surging a little bit. Before that it would buck bad on WOT in 3rd 4th and 5th.... Could have been over boost and fuel cut off? All I know was that it felt nasty! Will be getting a new one soon. Also was seeing only around 22mpg before I broke the maf. Anyone got any pointers of things to check for intermittent power delivery and poor fuel consumption?

Will be looking for a turbo upgrade when I've ironed out these creases, does anyone have any suggestions? Was thinking of a KO4 as I'm using it as a daily but would consider an FMIC and something a little bigger if it would be ok for a daily? Also wandering what chip I should for after turbo mods? Anyone running a KO4 with GIAC?

Thanks in advance

Regarding the MPG is the temp gauge working and what do it read?
