Sounds like the tuner doesn't know what he's doing or you have something not hooked up right, belt slip something.

Making crappy power for sure! How many S2000's has that tuner tuned?

 

I'm taking it you read that thread I was talking about. That thread is why I passed on a berk exhaust for 300. Don't need the extra noise and specially if it isn't going to make me more power. Dude once I get my tune I'll post it in this thread but for as much boost as you're making you should be making more power. I think most would agree but you need to start to look for another tuner.

 

Mod back me up here since you're in the 400 range how much boost are you making?

 

I'm using the vortech v2 kit which usually make a little more than comptech kits but I'm at 406 whp at 12 psi.

 

Yeah guys. I really don't know what to say. They have tuned one other supercharged s2000. The tunner is from Beyond Redline in green bay, wi. So far I think they are doing a good job. I will clarify that I made 317whp today after they put the 2.5 bar map sensor on and rewired my stock fuel pump. This was before I knew I still had a stock pump. I always thought I had a walbro 255 in there. But I brought my extra one just incase. The tunner didn't change anything except switch the stock fuel pump to the walbro 255 pump and disconnected the exhaust system by the test pipe. And it made 352whp. There's still a dip at vtec, and it isn't the smoothest, but he decided not to tune more since I said I will have them install my 3" header back and then fine tune it for the last time. I will post a dyno sheet of the 352whp and the 330whp tomorrow. I'm a little confuse myself. ????

 

Are you still using the factory cat or you running a TP? Cat meltdown turning into a blockage has bit several SC guys in the past.

 

Had a TP the whole time.

 

I'd look for a different tuner personally.

 

I guess we'll find out next week when I officially put on the 3"inlinepro exhauat system and hop back on the dyno.

 

Yeah, I've read that too. Not sure why my car is making such little power on a small exhaust.
