well thats all the performance mods i have done for now, but now im seriously thinking about not doing any more mods

something has to be wrong with my car, i thought stock #'s should be over 130's on a DYNOJET, but besides the #'s whats up with the curve? is it not suppose to be close to linear?

and they told me im running lean, it just wasnt my day the rag they had put on one of the straps burned up!!!!!!!! at first i thought it was my car , but nope it was the rag, shzz caught on fire i think.... danm and thats not the end of it, later on in the day my car started to make a whinning noise(kinda like the stillen supercharger) as i pushed the gas and raised the rpm's it whinned louder, danm im pissed .... good thing i caught my mechanic before he left so the car is at the shop right now , he said it might be a belt or a bearing... fuuuuudddd more money into the z

well heres the #'s 210 rwhp and 210 rwtq

im in for any suggestions guys, please help me keep hope in my z

did you get a tune?

 

no tune, im seriously considering it now with all those spikes!

what do you think bro

 

but i dont think i have ENOUGH MODS for a tune to be worth it right??

 

Looks about right

 

you really think it looks good?????? what about all those spikes

 

Its only about 15 hp low, no big deal.

 

5AT DEs dyno around 240WHP stock. But then again, I have no idea how oddly calibrated that dyno you used is.

 

Looks like you're running too lean and the ECU is pulling timing which would explain the drop in tq/hp up top. Get an Osiris tune and fix your A/F's.

 

^+1. Running above 14 to redline on a WOT pull is not good. The good news is that you have lots of hp waiting for you, if you haven't already broken something... That big dip after peak torque should tell you something.

 

Alright guys
I started looking around shops so I can get it tuned with osiris, but I thought I should have been fine without a tune since I have almost no mods, I thought the osiris is suppose to bring multiple mods together..... I know every dyno is calibrated diff.... But man 210 is pretty low especially since I have 2 well known mods that + rwhp

 

Sorry for the double post...... Danm blackberry lol

 

As previously mentioned the issue is that insane torque drop, not the overall numbers. Get tuned before you blow up, and no more WOT runs until then.

 

Your car would benefit from a tune without any mods. The tune makes the ECU think performance, where as the factory makes it think good economy (as good as it could be) and emissions.

 

Alright well I guess I'm going to have to tap into my fi $$$ that I've been saving
Ill find out today what's wrong with my car since something broke already... So ill go from there

 

OP, we're the same.. the odds that we ended up with a factory beetle than a factory freak.

on a dynojet i made 210whp, 209wtq. and after spending couple of grands, i'm running 304whp and 290wtq, while i'm suppose to be running somewhere around 360-390whp.

IMO, sell the car, get a better one. that's what i would've done if i only knew.

 

Danm...... I've been thinking of selling it but I've put too.....toooo much into the car already..

 

sell it and get a better one, so you don't regret spending more for less gains.

 

Idk yet... I want to try another dyno ... One that's had z's before so I can compare

 

you've got less than $300 in mods
