Inexpensive or "free" speed mods 03 Sedan

The stock programing on the 1.8t, 2.7tt, and especially the direct injection 2.0t is no where near as aggressive as it could be. 1.8ts can gain almost 30hp, and 2.0ts make almost 300ft/lbs at the crank with just a chip.
Plus those engines are pretty strong, e.g. 1.8t stock internals can handle well over 300whp.

The 1.8T is a good motor but has sooooooo much lag.
My friend had a S4 2.7TT which was a lot better.

Around 450 wheel right now on the stock block and going to build it next month with hopes of ~525-550wheel hp on pump gas and ~600+wheel hp on race.

Huh? Lag would not be a word I would use to describe a 1.8t. Maybe the big turbo ones, but the stock k03s is so small that it'll spool right up.
I liked my 1.8t, but that engine seriously lacks top end with stock boost, once you're chipped and around 22-23 ft/lbs, it become a lot more fun.
You're 100% right that the 2.7tt S4 is sweet though.

I just drove my friend's 05' (I think) 337 GTI wit the stock turbo, chip and exhaust and it had a TON of lag. I could push on the gas, take a drink of my soda and put it down before the boost kicked in. Everyone has their own opinion of what a lot of lag is so maybe it isn't yours but that is mine.
My car idles at 850rpm, even in 6th gear at 65mph I can step on it and be at full boost (~10psi) well before my friend's car if he downshifts to 4th.
Yeah, his S4 was awesome. He traded it in for a new one when the V8 came out. I like the look of the new one better but IMO the 2.7TT was better.

z tube is only $50 and doesn't add any power but it sounds very nice. A coupe midpipe will loose a lot of weight sound nice and seemed to free up a few hp. Can be found for $100-$120 used on this site. I know how a feel about coming from a muscle car to the G. I had a 708 RWHP 00' GT Mustang before my G
For free you may do a coolant bypass mod on the G's throttle body I know my LS1 Z28 friend did that on his car. Usually this mod comes with an upgraded plenum spacer kit which would be my next power mod.

Edit: You'll have to forgive me, coming from the VW world, I don't really know jack about the G35 or VQ, so when I find a thread that I can actually comment on, I jump at the chance.

Haha, I gress that's the differnce between a 1.8L 4-banger and a 3.5 V6. Anyways, back to the question at hand

No his car is fine, I have driven a few in the last few months and they all were like that. I'm just spoiled.

Trade spare and jack for fix-a-flat- sounds like a "jingle"
Remove everything that isn't needed, remove door panels and gut the doors, rear seats, A/C, stereo/speakers/amp, air bags, carpet/undercarpet material, trim, you could remove the hood, trunk lid, and doors altogether if you're really hard core. Wear loose cotton clothes and lightweight shoes- no socks. I bet you'd be in the mid 13's for free that way.
