Just tuning to get as close to the 11.50 without going under.

Re: How to reach the 11's

You should have made the road trip with us to Cecil last month. You would have gotten very close to the 10's. The air there is really good.

Next year, remember me telling you I still had the slipping 4l60e, small injectors, and base tune in there so I wouldn't have even made it down there. The 11.3 now in my sig was unexpected. I knew the trans was bad and injectors too small, I only went to log some WOT numbers and ended up with an ok time out of it.

Re: How to reach the 11's

Just thought I'd update. I did make it to the tens this year with the mods mentioned in earlier posts and about 150# weight loss. Best of 10.87 as of now.

Re: How to reach the 11's

So you ran the 918 springs with the 280XFI cam and didn't have any valve float issues? Or did you have to swap the springs out?
