Dyno N55

I had my car dynoed it's n55 with everything stock besides jb4 stage 2 bms intake and ER chargepipe the numbers were 311 horsepower and 370 torque and stock numbers were 287 horsepower and 320 torque so was wondering if there is something wrong or I need more mods to increase my horsepower thanks

But even if I get downpipe it will give me like 15 whp so it's still not much cuz the jb4 on completely stock car should give me at least 50 whp and 70 torque right? Since it says that on a completely stock car you will see a gain of 60 whp and 80 torque?

I doubt that! That would be big numbers for a stock car... To drive map2 you need modifications!

I know exactly what you mean bro. I got the jb4 and honestly barely felt any difference and I was expectin to gain 60hp. Everyone has raved about how much power you feel. I will be getting downpipes next, hopefully that makes a difference.

Post up the dyno chart. Peak numbers are only part of the story. Most cars gain the "up to 60rw" at a lower RPM than peak hp, around 4500rpm.

I'd love to see what your resolution is. I just got a JB4 for my N55 and intake and although I love the sound of the turbos and the gain it definitely does not feel like 60 hp. I hear its good to get downpipes but also must get charge pipe to run map 2. I ran map 1 for a day and now switched to 5 looking for more power.

U won't get the power ur looking for w/o catless dp's and a chargepipe . I would invest 25 dollars into the flex fuel wires if u have access to an e85 station. Car feels amazing w/ those mods. And don't forget to do the clutch delay valve delete

I think I'm going for downpipes And I already use 50/50 e85 and 93 octane mix without the wire so I'll keep that just need downpipes will let you know when I get them on the car
