Default thanks Tom!

I still don't understand why Vishnu's dyno produces such low max numbers though...didn't you say a 996 turbo ran on that dyno at one time or another? Were you able to see the results from similar power outputs from other cars? Funny, I was talking to the Vishnu guys a couple weeks ago about carrying their stuff for the WRX's, heh

Default Impossable to compair 2 different dyno's results but if you look at the....

power curve your power peaks at 5,000 RPM's

That means you still have some uptapped power in there somewhere. Power peak should be much higher on 93 octane gas.

Default Re: Its a 5-wire 02 sensor...

Advanced Tuning Products has a dynojet around the same area.

Vishnu's dyno reads a little lower then the dynojet but nothing too substantial.

All dyno's use 5-wire 02 sensors stuck in the tailpipe usually. I'd run as far from a place if they were tuning cars not on a wideband unit.

Default My intent was not to compare my numbers to yours..

I was putting them up to show what my car did on the our dyno.. Again I did 244 as a stage II and now I'm up to 352 thats an increase of 109hp
