well boosta, it's hard to boost a whole lot more than the S1 kit due to the limitations of our fuel delivery system. 16-17 psi seems to be the most consistent number that i've seen. You CAN hit higher boost but beware of that little bastard called greed. When you have a boost controller it's all too east to jack it up. It's always a good idea to consider gaskets when increasing boost. But unless your hitting over 20 psi consistently i wouldn't be that worried. I also thought that the new PCM was a whole new unit, because if it were a "chip" the aftermarket companies probably would have cracked it by now...
Yes, stage one is a great bang for the buck mod. But as i'm sure alot of people know, it's not my thing. If you plan on slapping on a stage one AND THAT'S IT you're laughing. But there have been situations where the S1 would fight other mods and reduce their gains as a part or as a whole. My suggestion would be ....
1- A good boost controller
2- Full exhaust
3- Good air intake
4- BOV
I know this is more expensive that the Stage 1, but i think it is more tunable and will make high horsepower and torque more attainable in the future...
