Yea! got your baby running Great job!!
I love purple :)
My tuner said every dyno will run different, it can depend on the make of the dyno weather, sea level, location etc. He said his always shows really low. and said you can go everyday and get a different reading using same car same machine, It's really just the best guess option we have. So mine could be 350 hp he said hard to get an exact number.
My tuner refused to do a e47 tune, He said ethanol is to inconsistent to tune for right now here in Calf.
Methanol would be even better

I'm running 245/40/18 Cooper RS3-A's on mine.

I'd love to run a drag radial at some point, but with my luck I'd break something first time I try to launch.

Dyno numbers are just numbers... every dyno is different unless it's in a controlled environment, barometric pressure, air temp, humidity, has a calibration procedure done regularly... you get the point. Use the same person/dyno to measure progress, gains and loses. Most (street) tuners will use time to get from one speed to another to measure gains or loses as well as reading the logs of a run and that is somewhat inconsistent as well depending on the weather.

black tara, just curious do you have a copy of the tune you have now?

At least you've got a "responsible" tuner. Some will just GRENADE parameters trying to get more power than available. Good to know. Hopefully I get the bumper on before work and I can take a treat ride finally. Even though it's pouring here today.

Well I almost got it out today. Bumpers on, inner fenders on, got it out in the driveway only to remember I still have the dealer temp tag!! (Palm to forehead)

So tomorrow, with any luck, we'll get to drive it. Straight to e check (fingers crossed no CE lights) and then on to the BMV for plates. Here's hoping!

Was just curious to see if your tuner gave you a copy of the tune. If/when you get HPtuners I'd be happy to help but would need to see what you have 1st. HPTuners forum also has a lot of helpful info. Dd you have it done locally?

He lives about 90 minutes from me, I would love to found someone closer, but he came highly recommended and I wasn't about to just let anybody with HP tuner work on my car.

Update on the project. All codes cleared! Took it in to a local shop with a tech 2 and had the steering recaliberated. Now my display reads information rather than service codes. The best part, we're exchanging services.

I noticed the tech had to keep flipping over the CanDi module (weird) I said it looks like you've got a broken wire or bad connection. I can fix that no problem. I'm going to repair their cable and in turn they cleared my codes! Nice, that'd never happen at a dealer...stealer

Thought I'd do a quick update. We had a busy weekend. After I got all my codes cleared and everything was up and running. Decided to fix a few things bothering me;
1. Charge pipe coating (was black crinkle powdercoat)
2. Raise Intercooler (sits 1/2" below bumper)
3. Increase wastegate spring (currently set to 8psi)

First up, pulled all the charge piping and intake tube. Tried sandblasting for about 15 minutes. Still couldn't get to bare metal! ZZP has some good powdercoating. I ended up using Aircraft Stripper, A LOT! Probably took 6 hours to get most of it off. Dropped off the pipes today so hopefully we'll have em back by the end of the week.







My ZZP IC brackets needed to be modified to allow me to raise it 1". Drilled in some slotted holes. Raising the IC that much caused clearance issues with the bumper frame. Did some handiwork with 4" grinder and welded the pieces back together. Haven't fit it yet, waiting for the POR 15 to cure.



Just needed a bit more room here...(both sides)



Here's what's left.



I've been easy on the new motor and turbo. Got about 700 miles on it now. Time to have some fun. I wanted to increase my wastegate spring pressure. When I removed the wastegate I found I had really been taking it easy, I only had the 8lb spring in there! I tried installing the new springs (now it's 3 instead of 1!) But couldn't get it even without trying to blow the M4 screws off. Luckily I have a 100 ton press at work and that made things MUCH easier. Now we're set to 23.6lbs on the wastegate relief.
