Finally got my first boosted car. Good old 97 gst with the 16g turbo at 16psi, 272 cams, 550 injectors, safc2 tuner, walbro 250, or is that 255? I don't know but the guy told me 250. It has a full 3" exhaust from the turbo back, it does have a cat, and it does have the ARP head studs. It has a pro-comp ultra lite air fuel ratio meter and when I stomp the gas it's right before the rich zone and often flashes green. When I am just driving normal I barley see the fuel air meter move at all and is usually in the lean zone if it does come up. Does all of this sound normal? This car also has no power steering, the seller said removing it added 10hp, , I almost lost it when I heard that. I mean I could understand maybe a 3hp gain but no way 10hp, . I am a motorcycle mechanic and know very little about turbo cars, any help is much appreciated.
I got the car for $3900 and it was out of tune from the 4-5k rpm range, but only in 3rd and 4th gear. Car pulls hard in all gears until 4k rpm in 3rd or 4th and looses all power. The seller told me its just 3rd and 4th gear being short and I needed to shift, I told him he's lost his mind , this guy...smh... I noticed my air fuel meter going very rich at the time of the power loss. So I started reading and reading about the safc2 tuner and tried to work out the tune. By trimming more fuel away in the 4-5k rpm zone (At -33% now) I was able to get the car to pull all the way through 3rd and 4th gear. For some reason now the tune issue has jumped into the 1st gear where it was not before. Its losing power at about the 3k rpm in first gear only but more so when the engine is cold. I have the tune so good for 3rd gear I am reluctant to mess with it anymore. Also, the 1st gear seems to pull hard once I've been driving for a while and every things nice and hot but when I first start the car pull out of my road I stomp first gear and lose power at 3k rpm. I'm not sure if this is normal for a supped up turbo car or not.
My safc2 Hithrottle settings are as follows, 1000rpm @ -12%, 1600@ -16, 2200 @ -20% 2800 @ -27%, 3400 @ -28%, 4000 @ -33%, 4600 @ -37%, 5200 @ -38%, 5800 @ -38%, 6400 @ -39%, 7000 @ -40, 7600 @ -43%. Do these numbers sound okay for the mods I have? It really seems to pull great for the most part.
I'm from Hagerstown MD and everywhere I call for a dyno tune turns me down when I say I use the safc2 tuner. I don't know why they would since ignorant old me can even make improvements but its still not perfect and I've been slamming 3rd gear around hear for the past two days straight. I really don't want to slam 1st around here since it peels wheels every time.
Can someone help me tune this thing with the equipment that is currently installed? Do I need to buy a fuel pressure regulator? A person I talked to said he has a 450hp eclipse with out one and it isn't 100% necessary. Does anyone know where I can get a dyno tune around here? I think I know where they get the name tuner cars... all day tuning.
