We had a lot of problems getting the car to make more power. We installed the ABC (just a bleed valve), but it wasn't clear we were gonna be able to get the boost up with that, so we slapped an MBC on there. That let us get the boost necessary, but it's manual
After we got the boost straightened out, the car just would not make more power. Nathan suspected it might be the stock BOV leaking, so Jermaine crushed it. May have helped a bit, but still seemed a little off, so an RFL went on. That I guess made it predictable, but still just hit a wall at about 325whp.
So the final results on pump gas were 325whp. I suspect it had more in it - I think TurboXS tends to tune nice and safe - Nathan said he could get a few more horses, but it would take a while. I said let's call it a day for pump gas. Boost ended up at about 22psi. I need to look at a log and see what the MAF value is to see how much air is actually flowing.
Next went the C16. Boost was cranked up to about 26psi, and it put down 375whp. Nathan and Jermaine both seemed to think it had more if I wanted to crank the boost up higher, but I didn't want to push it.
So we stopped at roughly 325/330 on pump, and 375/380 (hp/tq) on C16. Not tooooo bad, but I was really hoping to make 350 on pump and over 400 on race gas.
The car seems to feel pretty quick, but it's tough to tell. The BOV makes things really weird when shifting or just letting off the gas - seems like there's much more of a jerk than their used to be, so I think that's throwing off the butt dyno.
My car may actually just be a dog, though - on the txs stage 2 base map, where otherwise stock STis (Turbo back + utec), people tend to make around 280-290. I made about 275 on that map WITH the SR50. So either the dyno was cranky, or I have a dog, or the new turbo just threw off the basemap. I didn't have a chance to actually drive it hard with the new turbo to see how it felt before the tune.
But I picked up more products from the turboXS line - I now have their intake, exhaust, utec, boost controller, blow off, and the new Tuner (as opposed to the old, then new, Tuner Pro). I'll stick that in and maybe futz around with the maps a little bit. Next comes a front mount. After that, GT-35R
