I have an 2001 SS M6 withe the following mods, car is tuned in SD Maf is currently disabled. Current Dyno puts it at 436Hp at about 6300 and 392 TRQ at about 5000. I am looking at suggestions about getting my Torque numbers up? Thanks in advance...

Higher compression

 

Yeah, higher compression followed by higher timing. Depending on your setup, You might not be able to increase either of those by very much though....

 

mill the heads 30 and get a ported fast 90/90

 

Were the heads milled at all? What head gaskets did you use? Of course the problem will be with that duration you will most likley have to flycut to maximize your DCR (mill the heads and .040 gasket if you have not already). On the flip side you will gain tq and consequently Hp EVERYWHERE. An easier option may be to advance the camshaft a couple of degrees, this will shift your entire power curve down a little and will most likely result in more tq and it will come in sooner, but your peak HP will most likely stay the same.

 

I am not sure about all the specifics of the car I got it this way. It was done by rapid motor sports "Stage 2" heads and cam package. They are ported and polished 241 castings. I haven't gotten into the tune I think the timing is around 25 or 27 but again haven't gotten into it yet. I am not really looking to open up the motor just bolt on stuff and tunning/ If I open it I am getting new heads, but that will be down the road...
