thank really sounds incouraging zzzya ..........to give you an idea of how i know i have lost the low end.....i ran my friends volvo this afternoon on the freeway from a 50+ mph roll, dropped into 3rd and lost ground.....he got about 1/4 car length and as the rpms climbed thru 3000+ the G started to pull harder and pulled about 1/2 car before the shift into 4th, then i shut it down (we were coming up on some traffic)....before the dual exhaust it was not a contest at all with him........i am working on getting a dyno this weekend or next and then a TS flash to get that torque back!

i also plan on cams at a later date...........DIY? or have a shop install?

 

I was looking at the sportz magazine exhaust shootout, it showed the injen to have a little dip in torque before 3k, but it comes above stock by 4k......

 

I have BFGoodrich g-Force T/A KDW 2 275/35YR19's on 9.5x19 inch Volk LE37s (+22 offset) on the rear, with Nismo S Tune Suspension, and I have never had any problems with rubbing.

 

yep vfr350........thats exactly what it feels like.........i made an appointment tommorrow at Carboys for a dyno......ill post the runs when i get them scanned

 

Thats what me and a lot of people have. 245 in front, 275 in the back.

 

..it said Stillen and Nismo showed good gains in TQ throughout the entire power band and the rest of them lost some down low.

...that was one of the reasons I chose Stillen...that and the fact that it's not supposed to be that much louder

 

ok guys..........here it is....a little disappointment and confusion for my first dyno ....but it was 102F with 32% relative humidity and when i asked the "technician" if he had any training he said "why no, anyone can run this equipment"....it was dynojet run at carboy in houston

I have a 2004 g35 5at and all 3 pulls were in 4th gear........

so.......it seems that i have bone stock hp and torque numbers with about $2100 worth of performance mods.....ztube, 3/8" spacer on the intake side....headers, high flow CATS and Injen exhaust.....i am still going to get TS to reflash the ecu to "dial in" these mods.......but the dyno seems a little suspect to me.......there is a dynopak up north at sgp racing that i am considering for a comparison.......how about some comments? I could use some positive comments tho

 

Was the hood open or closed? I would think the car's cooling fans were on, was that the case on the baseline? Was your air on? What gear was your baseline done on? Hot hot heat.....

 

the hood was open and there was a fan blowing the "hot" air thru the radiator.....and the engine fans were running as well......4th gear all 3 pulls

 

one thing i noticed on the torque curve.........looks like i should be shifting at about 5000 rpm!........i have been running the car up to redline before....what do you think? is it more important to keep the torque from dropping off to keep the acceleration up?
