As far as my numbers...I'm not sure what they really are. Those numbers did not hold up at the track. Highly disappointed. I went with another tuner and it's a totally different car now. Originally...I could feel the car was a little faster..but I wasn't blown away and was seriously regretting getting the procharger instead of a PD system. But now after going with another tuner...the cars feels like a beast. I mean now I can feel the 200 more HP. After my first run datalogging, I actually pulled over and had to catch my breath. I was freaking out as to how much faster the car felt. 6 months of headaches solved in one night.
heading to the track soon. sorry to ramble.

I love hearing stories like that because I've been there too with the exact same thing. Bad tune. It wasn't a 200hp increase, but the original tune.. I was legitimately very upset. Then I decided to get another tuner because I knew it couldn't be right, it felt slower, which may have all just been in my head, but yeah, it certainly wasn't right. New tuner and it felt like a totally different car. I was all smiles. So, I can relate somewhat to how you felt after the fixed tune. Which was awesome.
I didn't know if 305s would fit or not, I think that Nittos normally run a little more narrow anyway. I'll definitely consider them now. I'll be buying whichever tires in March, because like with you, it's currently staying in the 25-35 degree range here and I don't wan't to feel like I'm driving on greased up lunch trays. I've been leaning mostly towards the R888Rs, but I would like to see your track times and hear how they are on the street for sure with the 555Rs. Thank you for for responding with some actual helpful input to my question.
