READY FOR SHIPPING , TAKING OUT ECU TOMORROW AND SEND IT OUT BY SATURDAY

 

Just placed my order! Anxiously waiting for the email on how to ship!

 

Just installed my computer, car has been sitting for a few months. Car started and no check engine lights. So far so good!

 

So far with about 500 miles, the tune stays and my god.....I have no traction from 1st to 2nd. I am wheelspining..... My 255 s04's still have at least 70% life. I really need to find some stickier tires. It's best to leave traction control on for my part. Anyone else have traction issues?

 

^^^^^^From the feedback from guys it looks like anybody with stock width tires are going to have major issues keeping traction! Looks like it's going to be almost mandatory to upgrade to wider sizes and stickier rubber with this tune to keep any kind of traction....

 

I'm stuck on my snow tires (245 width) right now it's absolutely miserable. I can't get traction at all to even feel any power. The few times I have though in 2nd and 3rd have felt really strong. I'm looking forward to hitting up the track April 1st when it opens. I have a feeling breaking into 11's with full bolt ons and a tune will be a lot more common now.

 

I'm running 275/245 Michelin PSS and before the tune I was already having traction issues. Now with the tune is even worse. I'd like to go with 295/255 PSS but I'm not sure if they'll fit in the rear with a fender roll since my wheels have a 42 offset. I'm also not sure if anyone would buy the set of PSS with about 3500 miles on them.

 

+1 having traction issue's and I'm loving it haha I'm on a 285 on a 19x11 need to try 295 or 305 and see if that helps haha around 150 miles on the tune and it just keeps getting faster after ever pull ...with my apexi throttle controller on the response ridiculously fast

 

Ugh, that's gonna require fender mods.

 

305's require a slight rear fender roll, no real modification.

Plenty of us have tried it already on boutique rim setups.

 

What offset are you running?

 

Not 100% sure but I'm going with 295 just ordered them and my fenders are rolled already from when I had 20''s ...

 

We don't have to worry about that at our altitude haha

 

Interesting... what brand/model are you currently running? Are you having traction issues on hard straight line acceleration when the tires are cold, or mainly when taking hard corners and applying the throttle?

If you're having traction issues on your massive rears I wonder how others will hold up. Right now I'm running a square setup 265 all around with Michelin PSS. With my wheel size I'm probably limited to running 275 max without modding fenders.

 

you guys have to think its still winter. it will stick a lot better when warmer weather comes
