Re: Getting a E92 323 Coupe in a weeks time. Need advice!
Hi guys, I understand your reservations on the matter. I've posted the dyno chart as I think words alone can't prove anything. I'm sure you've heard intakes and exhausts adding 5-20hp but people are quick to say the improvements are "psychological", "on paper only" , " due to spending $XXXX", etc. I'm a pretty skeptical person myself - be it people or products, I only look at results. No point talking if can't produce credible information.
I can feel increased acceleration within the same rpm range of 1500-2000rpm. Plus the PBX is able to switch to original mode with no optimisation, throttle amplification so I have personally switched between the two to feel the diff. The improvements are really too significant to prove otherwise! The 323i is the same detuned version of the 325 engine so I had a hunch the box could optimise it to its original potential power or better.
With regards to the Nology plugs, well it's really up to individual preference as there are so many kinds of spark plugs on the market. I've used OWS plugs on my former car. Once the original plugs come to age, the engine starts to feel rough. With new set of spark plugs (regardless of brand), one should expect better performance, smoothness (engine oil change can only do so much).
As everyone here are experienced car drivers/modders, I respect each and every opinion and hope for healthy discussion on car improvements here. As I have no personal interests in whatsoever, I'm just stating my unbaised review of the product. I've gained much from reading up on the forums so i hope to share and learn more from you guys.
Cheers!
