*I got used to the 355's I used to tune, then send down to the dyno and have them find 5-10 ponies I missed, it finally hit me that every engine is ever so slightly different....*EB

You're right on that one, it even worse with toyota's newer EFI. When you buy a tuner from URD, they give you a base map, but it always needs alot of work, just because every MAF sensor is different (and how the engine is, re: timing/detonation)... so its a pain!
