Just bought one for my ATD from what seemed to be a reputable seller, and he claimed it was 140bhp. Fitted it just now and had a flat spot when I got to about 3.5k revs in 4th, and it's a bit gutless at lower revs. Now what I'm wondering is, do I return the ecu within 14 days and get a full refund? Or could it be down to a possible boost leak? Turbo spool is a little louder but egr is blanked off and deleted on map.

Cheers

Why? Why oh why did you buy from eBay? Send it back.

Ad looked legit, feedback was good. Had a 14 day returns acceptance so had nothing to lose.
