As I drove my back back from OC to Bay Area, I didn't feel much power as it would therefore I took it back to the same dyno shop that I did with my stage2. After 4 pulls...the avarage I got is 286 whp/281 tq. My A/F were 11~10 @6000K rpm. Mine stage 2 was at 283 whp/279 tq. The weather for both time are same (~65F)... Any recommendation ? thanks

Will try to post the dyno result as soon as I can get the scanner to work

 

you sure everything was installed correctly?

 

uhm... something is wrong. dunno what. /me subscribing

 

Where did you get the stage 4 parts installed at? Do you have a boost gauge?

 

I have mine installed thru Infiniti dealer of Van Nuys...I do have Defi boos gauge...It was reading ~8.5psi when dynoed but mine AF was like 11~10 @6K rpm

 

take it to Stillen, they're in Cali. They will tell you what's wrong.

 

dam, that kinda weak. that only 25hp more than i have n/a. somethings gotta be wrong. best of luck

 

yeah...seems to me this is the only option for now...waiting for Stillen to call me back to set something up

 

what are you using for tuning? there maybe something is wrong with the install and i would also assume you are running pretty rich. Lower power is better then higher boost + running lean and this thread titled "CRAP stage 4 stillen blew my motor" But good luck nate, and hurry so you can spank that vette! =)

 

I would have to let stillen look into tuning since it's their locked piggyback box
