OK before surprise you with my number, let me list out my mods

NM charge and discharge pipe
Wagner Competition Intercooler
K & N hi-flow filter
Quicksilver exhaust
NM Short Shift adaptor
NM torque arm mount insert
Alta blow off valve spring upgrade (with stock BOV)

I have the Manic Tuning Stage 1+ after all these mods and my result is


147ps (flywheel)


I don't get it, even I calculate the power lost, either 25% or 60HP, it's still lower than my stock HP which is 208HP, how is that? My car only have ~15000miles on it and I change my oil every 5000miles. Can anyone explain this to me? Thank you

p.s. The place I did in Dyno is different than the place I did the manic tune (I thought that way I can have a non-bias result)

 

All dyno's are NOT the same! Besides measuring either Wheel HP or Crank (flywheel) HP, they have different load and measurement techniques. It's always best to use the same machine when comparing performance mods. This minimizes the variations in different machines, leaving only normal environmental and calibration variations.

 

Does the car feel faster after the tune? or slower?

 

What does your butt dyno say?

 

My car feel more linear than before, and the pop sound is more loud in sport mod. However I not sure if I feel faster. My manic tuning people say it's not going to change a lot since i am not replacing my turbo nor downpipe. My dyno guy says they don't know (there are not many JCW around my town).

 

Oh and one more thing, it's definitely slower than chipped my car with race chip pro (but without any mod support back then, chipping my car caused malfunction of my spark plug)

 

Getting any misfires or anything?
Manic tunes recommend NGK 1422 or NGK 91448 Spark Plugs

 

Yes I got the NGK spark plug when I do the manic tune

 

Did you contact your manic dealer?

 

This! To really see what kind of power you could have gained, or lost...you need to test before and after on the SAME dyno. A dyno could easily be off 40-50hp.

 

Ya.....now I know, the manic dealer didn't tell me I need to test before and after on the same dyno.

 

If you have the SRS switch you should have done a run in stock mode then switch to the A,B,C tunes to see the difference. Also you should monitor and compare boost.

 

But I don't have the switch

 

The switch is just $200 bucks. Definitely worth the price.
