Yep 5.3, not 100% but think it's 373s

 

Hoping for high 12s after the turbo.

 

Totally doable! My 07 did 2.75 seconds faster in the 1/8th on only 8.5lbs and it was a rear mount. Gears and converter of course.

 

Thanks for the info! My set up is similar to yours save for the cam, and I haven't gotten my headers & y pipe installed yet.

First I'm going to make a trip back to the track to see what improvement the tune gave me.

Then I'll have the headers and y pipe installed followed by a trip to the track to see what gains were achieved.

After that, my next step will either be a small cam or a converter.

 

The tune is what really woke the truck up, was a night and day difference. Headers and y pipe is really easy to put on just be careful when taking the header bolts off. Think the converter would be better than a cam.

 

Going to order Siemens Deka 60lbs injectors but can't find a straight answer on what orings or what size to get, anybody have an straight answer? Thanks in advance

recently ran mine on the 1/8 mile track. I still need a convertor and some better tires. left off idle, spun through 3rd. but still managed a 9.5. not to bad. lol

 

9.5 not bad? all the spinning not good,needed new driver or sticky tires

 

yea, lots of driver error, lol.
