If you think the shop didn't tune you correctly, talk with them. Did you get a dyno tune? Post your dyno chart, as that will tell us a lot more information than continually telling us that you put in a tomioka 20G with 1000cc DW injectors and a 255 fuel pump with headers 16 more times. And to those saying that there's no way a 20G Sti would run high 13's? Challenge accepted. I bet I could do 14's. or even 15's. There are so many factors going on. Maybe the OP was just having a crappy night and didn't realize it.

it is my personal opinion that anybody who mods to this level who can not tune their car themselves is and will always be a......
well.... there is a reason that so many of these cars never see 11's much less 10's....and blow up with such amazing frequency and it isnt the car or the hardware....no. |

20g turbos take longer to spool. Have your car tuned so the turbo starts spooling at 2500-3500 RPMs. Get a boost controller, can't believe you got a big turbo without one. Your mods will get you more top end power but you need more low end torque, throttle response, and boost. I'd recommend a protune instead of using an AP. Just use the AP to store your pro tune. Now you haven't really answered any questions anyone has asked. You may have a vacuum leak, you mentioned oil in your BOV. Get rid of the BOV, that could be your problem right there and it probably is. As expected your car was lagging in its spool rate with the larger 20G. Expect an increase in lag of 200 rpm or more if you have a crappy tune.
Sounds like something isn't right. You said originally that you used an AP for an e85 tune, then you said the guys at the tuner shop rushed your car because it was late at night. What dyno was used? What was the shop? What are your dyno numbers, where are your slips? Are you running old tires? Don't you know that STIs are not the best car for drag racing? You should try autoX, rallyx, track days, something with some turns. Last edited by DannyLerch; 09-08-2013 at 08:08 PM. |

Even car's from "tuners with years of experience" can, will, and do blow. It's up to the end user to do logs and ensure the car is performing to the best of it's abilities.

I'd even go so far as to say in highly modded cars stuff simply goes wrong. It doesn't matter who touches it, ****s still going to break. The idea is going to an expert engine builder, fabricator, tuner is to avoid as many issues as possible instead of learning everything by breaking it yourself. Preferably a shop that actually stands by their work. |

User error?
Someone had to go there. A 20G and E85 is a rather significant bump. To be slow would be a byproduct of how the new package is used. Some can be attributed to tuning, but for drag, I can't really see you low in the rpm range to care about lag. You would need to learn new timing with pedal work, but the rpms should remain sufficiently high where lag time would be quite low. It's not like you shift a gear and end up down at 2000 rpm. If you're going to redline, you're still quite high in the rev range and very much in the turbo's happy place for reasonably quick boost. I don't know how much you've done with the car yet, but I will note that the stock clutch is a weak point. With E85, you are very much pushing the limit of what the clutch can support. You will quite moderately slip the clutch when launching at high rpm. A couple of launches will overheat the clutch noticeably and worsen operation. As for the initial launch, you can't really put much more down than pre-E85. However, the clutch will hold statically once engaged, and you should see much higher acceleration from the car down the track. The tuner likely limited boost to within a level that the clutch supports, although E85 can allow higher boost. The only place you can really falter would be on shifts. The 20G isn't huge by any means, but it will be slightly slower to react. You need to learn to get on the throttle sooner on each shift to compensate. Even with sloppy shifting, you shouldn't be all that slow. We should be talking about something going from 230whp stock to around 400whp peak and a lot more torque everywhere, not a small gain in energy expenditure. In gear and the throttle pegged, you should have a pretty big difference in acceleration rate. |

I'd say your 60ft is why E.T. went up and the car isn't so much the problem. In general, for every tenth you add on to your 60ft it will add roughly 1.5-2 tenths to your E.T. I had the same problem with my last car, made it faster and ran slower because made a decent 60ft that much harder. I would say relearn how to drive/launch the car because it probably drives a lot different than when it was on the old set up and then see what you run.

Where are the time slips and dyno sheets (stock and mod)?
If you say something like you don't have a dyno of your tune, then that's just plain stupid on your part. |

Does anyone know what turbo he has, if he upgraded the injectors, and what about a fuel pump?
Anyone? |

How much did you weigh before mods and after mods?
I think we might have a chance at this problem |
