My question is what is the proper (as if in general) way of upgrading a car, to match certain PP or HP limit in a room? Keep in mind that I'm asking only for the REVERSIBLE upgrades on the car - ECU, turbos, air intake system, etc, NO weight reductions and engine upgrades!
For example you have a car that is 552pp and has 165hp and the room is set to max 570pp? What is your preferred way of matching the PP level?
I personally prefer to use:
1st - Intake system
2nd - exhaust system
3rd - ECU
4th - turbo (if any).
And drivetrain and suspension of course but since they don't reflect PP :indiff: they are not part of the question.
 
I usually add intake and ECU first and exhaust or turbo only if I can't match the PP any other way (unless the exhaust actually improves the way the car sounds, which it rarely does).

If the handling goes too loco (for example Stratos) I add a fixed sports kit. If that doesn't help, I'll dive into the fully customizable suspension and try to make the car work that way.

I always add drive train upgrades as well apart from LSD. I only add LSD if there's a problem with the stock configuration.

gt5 loves rpms.

always add the mods that increase peak power/rpms first

ie. ecu, catalytic converter, exhaust.

It really depends on the car and power limiter usage. I've found cars that were slower despite extra power from RPM adders instead of non-RPM adders.

Of course the more PL is used, the more RPM adders will help.
High RPM turbo's can be very good for PP as well. (Usually much better than low or especially mid-range)
 
Remember to route your power, the three main things are; ECU chip, one of the exhaust kits, and the racing air filter
 
Finding, and utilizing the right turbo is always a good start for me. A high rpm turbo will give you more power, but if your hitting the peek of your power ban at mid to low revs, you'd be better off with a mid to low rpm turbo (these are rare in GT5, but they do exist) :dopey:
 
So, as I suspected, there is a difference and in some cases some upgrades work better than others. :) Glad to see some feedback.
So maybe I underestimate the ECU part. If it really routes the power better. This is logical, I must admit. Hmmm.

that's because the RPM adders stretch the powerband. take for example, a turbocharger. If you fitted it in a car that revs at about 6500 RPM, you'd get a sudden surge of power, because the turbo's power is compacted whereas in a high-RPM car, you don't get a surge, but instead a smooth delivery of power. The turbo's power is stretched.
 
well i fully tune everything for the vehicle, what's the point on putting a limit on your car or even half tuning or de-tuning your vehicle. its like i was in a clio cup room the other day and the host put a limit on the pp. and i asked my self why? people have different tunes and different pp. also why restrict the car if a car has 350 bhp why put a limit to 300bhp? but i suppose its up to the person, the host and everything else. in my opinion people who de-tune the cars on a large scale should be smashed out of the way by the trans am :)
