you are right! i need to go for a retune with Sam. i have made alot of changes since my last tune and those hp numbers are before my latest round of mod's.( exhaust, test pipes , mrev , re-pullying etc. etc.) my A/F's are around 10.0 to 9.5 through the rev range. rich is definately better than lean right now but bad for power. that power number posted on my sig was with 10 psi.
ooo ok i thought they were with the 13 psi im gettin my charger back friday with the 28 tooth what kind of numbers did u put down with that and if you are going to upgrade go witht he t-trim and a 2.62 pulley
have not dynoed and tuned with the 13 psi yet. i have just done these mod's recently. that is why i only rev to 6600 rpm at this time. the 13 psi hit's at 7100 rpm, i am not going to rev up that high till i get the tune done. did it once just to see what psi i was going to get out of it.

Thanks man.

If it's not a bother, can you PM me and let me know how it's going once you start working on the Si trim setup and whatnot. I am definitely really interested in upgrading to be able to take advantage of our higher revving capabilities and make lots more power! Thanks man.
Thanks man.
just called vortech and found out the Si trim upgrade is available. all i have to do is send in my current V-2 SQ trim head unit and they will install the upgraded Si trim compressor wheel. other wise all internals and the diffuser assembly stay the same. cost will be $329.00. i guess i will be the first one to roll with this! supercharger is comming off this weekend and being sent out to vortech for the upgrade. i will keep you guy's posted on the outcome.

But if everything works out for you, I will definitely be upgrading to the Si trim and your pulley setup too!
