Its been a month and im really liking my f sport but i think it needs another 30-40hp
Is there anyway to get more hp without voiding the warranty ?

Get in line lol. Besides negligible gains via intake, exhaust, etc. there is no way for hp gains under warranty.

Being as the GS is a NA engine I don't see too much of a window for any serious HP increase with just a tune like a FI engine might realize.

If TRD would come out with something like a supercharger pkg that would be encouraging.

very very unlikely, sad

I was looking for more torque myself but I've learned to drive like what it was meant to be, a GS (Grandpa Sport).

The best you can do is try to lighten up the vehicle so it can match the IS. If you can reduce weight without sacrificing the size and luxury, you are golden. Wheels can be done...that's what I noticed the most. You can go with coilovers to reduce some more weights. Make real carbon fiber replacements on non structural parts (don't know any yet).

use Lighter battery. Remove the spare tires. Remove floor mats and replace it with lighter weight floor mat. You can start replacing metal parts with lighter but stronger parts - but It's pretty hard to find them on the 4GS.

All that would reduce weights without sacrificing luxury while improving performance.

LOL on the Grandpa Sport. I agree that weight savings and improving the car's handling is the only (current) way to go.

I guess I just need to be happy with what I have right now,
It sucks tho there is no option like BMW M package to get 20-30 more hp.
I wouldn't ever buy BMW because they are way overpriced for what you get but I think option like they have,especially on f sport is must IMO.

The M Sport has the same turbocharged 6 the 535i does, and both can benefit from aftermarket tunes that will raise boost and with that, both and HP/TQ. The GS has none of that latitude with its NA engine.

Personally, I have more respect for the GS' engine, as it is doing quite well with no boost whatsoever.

The Bimmer 's 6-cyl wouldn't do so well with out any boost and the GS would walk all over it.
