Should i tune my car?

[my95tsi]

Ok i only have a the stock t25 now and i'm finishing up my basic mods over summer by getting all the hard intercooler pipes and a downpipe. My question is if i should get an afc to tune it the best i possibly can with my stock turbo. I've heard from people that you can tune a dsm pretty good with the stock turbo and it gain alot of performance. I plan on keeping the t25 till i graduate from college so i'm going to have it for the next year atleast. I just want to get rid of richness that my car runs. I just want to tune it for best possible performance with what i've got.

u cant just buy an AFC a tune it. You will probably end blow it up since u have nothing to tune it off of. Do yourself a favor buy a pocketlogger,EGT gauge,boost gauge,A/F gauge (optional) then buy a S-AFC. Thats later down the road though just get the basic bolt ons. Tuning a T-25 isnt gonna get yo that much power since you cant push it more that 15psi and you dont have to upgrade your fuel system.

P.S.-I said the same thing that i wont upgrade my turbo till after college, ill just buy bolt ons. Let me tell you my friend BOOOST is very addictive :laugh:

I'm wondering the same thing, I run 13psi which creeps to 15 then falls off to 12 psi by redline. I'm getting full timing of 19-20 at redline. I'm not sure what else I can do. I was thinking about leaning it out a little too since my timing is good and I'm not getting any knock.

I got a question though, if my ltft are at about +4% does that mean it add an extra 4% of fuel while in open loop useing the fuel maps?

I have no fuel mods done yet.

Thats right, your ecu is compensating 4% to get the trims where it wants them, so you're a little lean.

Ok so all i need a is a pocketlogger b/c i already have all the basic shit. I'm really not going to get a bigger turbo till after college. I only have a year left but i have to drive 8 hours with my talon to get there and back. I don't need a crazy setup that make my drive more difficult or less reliable. Its already bad enough having to drive 4 hours back from school in a crazy Illinois blizzard with no paved roads and about 3-4 inches standing on the ground with a lowered fwd. you try an do that. I turned a 4 hours drive into 7 hours one way. Boost doesn't help either.
