How to improving a significant Performance?

Robyn90 · 03-19-2007, 03:59 AM

GUYS

I have E90 320i with some mods. I spend around 2,300 USD (it's a bit pricey for this kind of equipment in Bangkok) for ECU Remaping, Sebring Quad Exhaust System and K&N Intake but I cannot notice any significant improvement and sometime I think my top speed is a bit less from before.... However I can notice a slightly improvement in Torque around middle-range but I look for more than I can get from the money that I spend.

from what I have see in Dyno Chart and my experience that most Tuner claim that they can gain 25+ 30+ or 40+ HP from ECU Remapping. I think it's bullshit.

So anybody have any suggestions to increase my HP in my little 320i ?

better than all previous opinions
wait for the new m3
im sure thats a decent HP jump from a 320i.
then u dont have to spend money on power mods

FI is the cheapest way.

Guys

In my country, 320i is cost around 80,000 USD which I think I can already have a 335i or M3 in USA or UK as well....

That's the problem....

The 320i is not really a fast car to start with. I think you are going to spend a ton of cash trying to make that car faster. It's very likely getting a 328 or 335 will be cheaper in the long run.

That's an expensive one. Couldn't you try to get one by European Delivery? I wonder if that would have turned out cheaper?

The major factor is the imported tax which is around 200-300% for this type of car....

aren't there any thats locally assembled? Because i go to malaysia very often, and the 320i and 325i can be ordered to be assembled in Malaysia, so its like a lot cheaper, still expensive compared to US prices, but its not fully imported....

Robyn90 · 03-21-2007, 01:49 AM

Yep It's locally assembled in Thailand but GOV still have the policy for taxing such vehicle at high-rated...

Otherwise I can see lot of M3 in Bangkok already cuz we have to pay for normal 3 series in M3 price..... or pay for 525i in M5 price......

i know what you mean, when my dad bought his Audi TT in Malaysia, it costed him around RM$400,000 or USD $115,000, but it was fully imported from Germany

I'm got a 320i in M3+Completed Mod price same as you hahaha... Now i'm going to get the K&N intake system kruub!!!

Change the differential final drive ratio. You won't get any gain in HP but WILL get a gain in performance.
