i'm going to send my pcm out for a tune any idea whoe is the best? also looking at mounting a scanmaster in my dash vent,are they really worth the money? any help would be welcomed.

 

PCMFORLESS and MADZ28 are the two most recommended I've seen on the forum. There's a thread around here where people compare and contrast these two companies.

 

depending on where you are located, a member on here (foff667) does an awesome job with ls based motors. he fixed all my problems in my driveway for $50 which $700 of mail order tunes couldnt do

 

I am also debating which one tuner is better and yes the scanmaster is worth having as it tells if your running lean or rich and if getting the dreaded KR.Ialso had mine installed in the dash vent ans it is easily viewed there and more importantly looks factory(not hokey)IMO this item should have OE as it does tell you what is going on esp. on the 93-95 cars. Also try find as used one as i did.
