Default She's running

Well long time no update. Apologies. Waited and waited and waited for the engine but after 8.5 months I got it, didn't receive the engine until mid October. Got everything installed and a base tune done and fired it up for the initial break in stuff roughly 10 days ago. She runs like a top! Still driving like a sissy to not blow er up right away but everything it great, couldn't have done it without the info on this forum so I do appreciate it!!!!

Also put a short throw shifter in while it was all out too.

Also upgraded tp 6 piston calipers while at it

Glad to hear it's back together again.
Also I agree with what Jmilz told you about getting absolutely the best dyno + street tune you can get.
You do not want to do this again. Find a reasonably local and reputable tuner who others vouche for from experience.

Thanks, agreed, i looked all over for a tuner. Found one in ocala, base tune is great, I feel confident he can do the final tune also.

Default Finally got everything done

Car is/has been.done for awhile. First tune, found out the clutch was slipping but made 355hp/355tq at the wheels on a mustang dyno through thr stock headers and cats.

Well put a new clutch in it and let headers, pulled the cats and put an xpipe in.

Car is like a new car, 415rwhp and 400rwtq on a mustang dyno and runs like a top!

Thanks for this forums input and help!

How much of a difference from the Ls6 does it feel like.

It's way faster. My buddy in his bmw smoked me by like 5 cars with the ls6, I pulled him by a car. It's literally night and day.
it went 13.8@105 with the ls6 I haven't gotten it back to the track as I want my backup running first in case I break it.

Ok. Sorry, lol a little defensive I guess.
I put the car in the mid to low 12s now... hopefully another month or so to find out.
