on a highway drive, i smell a lot of unburnt fuel? most after i hit boost and then you can really smell it...but if cruising itsn ot as bad but can still smell it....car has a full 3 inch turbo back w/ test pipe....would tuning the car make the car run better ? also what could be causing this ?

tuning the car will make it run better and add some hp. but maybe not as much as, if you had more mods. your car shouldnt need tuning with those mods, its proabably your o2 sensor thats gone, or your afm needs adjusting. have you checked your timing or anythin?

If you think its rich, throw it on a dyno or get a wideband :) Most supras DO run on the rich side... I had to take ALOT of fuel out even on stock fuel pressure and stock 440cc injectors after getting my wideband to get it fairly lean during boost (11-11.5 afr)

I can't wait to get my tuning done by Intense Motorsports :)

Finally driving my car after 5 months, now a small break-in and then it's off to the dyno.

My car feels so damn slow right now........all the power is 4K-6.25K :(

widebands are so cheap these day for the cost of one tuning session at a shop you can buy one and do it yourself. why would you ever pay someone to do somthing you can do yourself
