I don't have too much experience with tuning (have not been on a dyno with my tune, so I can't say much beyond what the butt dyno says
), but here is my 2 cents.
I was going to go with Visconti's tune (this was before the car-fire fiasco), but I bought a cable from someone who used FA20Club's tune and he said they would hook me up.
Well, they did, kept in pretty good communication and it wasn't advertised as a one-step program. It specifically stated to send over datalogs to keep the tweaking going. They haven't failed to make an update when requested (had the logs sent over). Sometimes they respond to an email of mine near 1 in the morning. Most people don't work that late, so I give them props for putting effort into it.
Perhaps EcuTek does certify some bad tuners, but @
FA20Club.com is not one of them.
