I've bought a used wrx with a Link ECU. Not sure of the version or type of Link (but I have the PC-link), but the car has a VF34, STi injectors, walbro fuel pump, Blitz FMIC, upipe, downpipe, and a custom center section to the stock axle back.

Here's my problem: The car is VERY laggy. Excessively so, the car spools ~5.5k. It's fast, but not any faster than the average WRX with upipe dowpipe and a reflash (only, laggier, but it doesn't drop off like the stock turbo's). I'm not sure if this is a tuning issue, or if there's something else I should be concerned about. I have no experience with tuning, so doing it myself is most likely out of the question, but I would like to find out how I could maybe upload the map I have and have one of you guys take a look at it for me, to see what's going on. The car only sees a bit over 15 psi of boost, and idles fine at ~900rpm, but moves around a bit. Thanks a lot for any help at all!

some progress...boost is building quicker but there's a fuel cut at full boost...will somebody help me out?
