There was hardley any preasure drop, and yes im runnin the stock turbo. The new support beam and intercooler only way 35 pounds or so. The car is running better now the first test run was a little rough,(waiting for the ecu to learn the new settings). I think i runnin lean above 5000 rpm. My a/f gauge goes from being all the way in green to red, and then the cars seems to hit fuel cut off. I think theres just so much more air for the ecu to deal with that it just flips out. Time for stand alone. Does anybody have anything against the UNIchip?
