don't boost with the base tune - be patient.

 

just an update...the parts didnt come in in time to install them before my tuner went on vacation. so they finished installing them thursday and friday and will put in on the dyno and set a base tune on monday, thats when ill get the car back and post pics. everything is wired up though. the autometer Nexus guages match PERFECTLY with the stock ones. and the boost controller is mounted on my ashtray door. the shop did an awesome job. everything is very clean. i cant wait to get this baby back and post up pics and numbers. unfortunately ill have to wait till at least monday after next to get real fully tuned dyno numbers. but for sure ill keep this thread updated. cant wait.

 

soooo.....STILL didnt get my car back today :/

the tuner/owner is out of town, but they were going to get a base tune going and give it back so i have my car at least until my tuner gets back from vacation and he can do a serious tune on it. obv i am going to drive carefully and not at WOT.

well i guess there was a plug issue. they said one of the iridium NGK plugs they got was bad. they put the stock ones back in to diagnose and sure enough they were fine. so they are waiting on that.

when i got there they were messing with the idle. it had a VERY rough and rich idle and would die very easily. they said it was cause of my upgraded 660cc DW injectors. basically he said that the UTEC doesnt have a quick and easy way to just up the injectors from the stock size and they had to go in and pull fuel manually for the entire RPM range. ive never tuned ANY car much less this one, so i said that sounds right i guess. so theyre gonna tune it tomorro with a drivable tune and give me the keys. hopefully. **** i am getting so impatient its been like 2 weeks :/

 

I sure hope you're not at the beginning of a Turbo G horror story!

 

i really hope not. again i HOPE to have it this afternoon, but thats been the case for like 4 days now. ill update later.

 

ok so i just got back from the shop. MAJOR idling issues. it ran flawlessly on the dyno however. made 389hp 369tq @ 6.5psi. cant ****ing WAIT to get this car on the road.

but anyway, yeah so its got a MAJOR idling problem. like, it wont even turn over unless you give it a little gas, then itll just die if you dont feather the gas like right away. it dies when you come to a stop. the AFR was hard to tell cause you have to keep feathering the throttle, but when it finally would settle down and idle, it was at like 400rpm and the AFR was like 14.7. my tech thinks it has to do with the drive-by-wire throttle. he thinks the car is getting enough fuel but not nearly enough air at idle because for some reason the throttle isnt opening up all the way. we tried setting the 0% load column to -10, all the way to -30 and it just got worse. any ideas?

oh yeah, and the Z1 clutch is SUPER RATTLY. i really dont like it. at all.

 

Raise the idle and if you need a reflash to do that, you might as well scale properly for the injectors as part of that. You have to make compromises with the UTEC.

 

honestly i was thinking of switching to UpRev and Osiris but Ryan at Forged said they do like 80% of their TT installs with UTEC and almost never have any problems. im seriously contemplating paying like the $400 each way + tuning cost to ship it out there and let them fix it.

 

basically just an update....i talked to them this afternoon and they are recommending a fuel return setup. i talked to Ryan at Forged and he said you shouldnt need one unless youre making serious power, like 500+. thats generally when ive read all over these forums too. regardless what i do i have to wait till the tuner/owner comes back on monday cause he doesnt want them ****ing with it anymore. hes going to tune it fully when he gets back.

i was thinking about going with UpRev and Osiris and selling the UTEC but Ryan told me they do like 80% of their installs with UTEC and have like zero problems with it. either way this is a freaking headache.

 

so i got my car back yeasterday.

we ditched the UTEC and went with an Osiris reflash. the idle problem all but went away. it is a little lumpy still but no stalling and itsd a million times better. its getting better still with every mile i pus on the car.

we dyno'd at 7.4psi and hit 397rwhp and 377rwtq. after we iron all the bugs out we're gonna bump it to 9psi for a high boost setting for "special occations"

i am absolutely thrilled with the car. im at work right now so i dont have pics or the dyno sheet but will get them when i can. this thing hauls ***.

the only thing i really dont like is the Z1 clutch. its a 6-puck and a single-mass flywheel and chatters like CRAZY. its also a bitch to start in 1st. but other than that its ok. ill be upgrading to a better streetable twin-disk setup in the future.

ill definitely be updating this thread later though. thanks again for all the support and advice.

 

Who's your shop? There's not a lot of reputable people out here in Cincinnati, either. I need some options.
