I use pcmforless and am happy but would not hesitate to use madz28 either. Madz28 is in the Chicago area and pcmforless is near Philidelphia if you are near one maybe that is the tie breaker.

For the 92-93 Speed Density cars, I vote Alvin at PCMforless.

I had madz28 dyno tune my car and it went really well, first he sent me just a basic tune to break the new motor in on. He had the "over the internet" tune so close it only took two runs to finish it up.

I've worked with both of them, both are good guys. Either one will take care of you.

If ya need a cable, let me know.

I've been in many arguments as to what my heads flow. All I can say is that they were very heavily ported and I saw them on the flowbench. All of the intake ports flow +/- 300cfm and one got up to 313 @ .650 lift. I asked for 260-270 cfm, then we decided to go with bigger intake valves and by the time it was all said and done, they were monster heads. I also have a friend who's LT1 castings flow as much as mine do. Just takes a whole lot of work (his had to be welded where he broke through into a water passage.)

I would go with mad..but thats just because hes local (at least within driving range) and talked to him before. I have seen nothing but good things posted about him and that makes him a winner in my book.

Does MadZ28 do mail order tunes? My bro will need his PCM tuned for his 396 Blower beast...how much does he usually charge?

What is MadZ28's contact info?

I had a PCM tuned by Ion. I went from a 14.1@99 to a 13.8@103, and i'm still running a ported MAF against his reccomendation (it could be throwing off the tune a little). I'm hoping that once i get a stock MAF it drops down to a 13.6@105 or so, but we'll see.
