Pulls good, are you running on straight pump? No meth?

Yep, 93. That's why it's on 10.5 degrees, and will be leaned out to 11.0. Until I get some meth on it. I had that racetronix drop in 255 module with hot wire, and in 3rd about 6200 rpms it was starting to lose pressure. Switched to a 340 with hot wire. Not sure what it's making for power, we logged a 25-95 pull at 5 seconds though, but my tuner said it was 85% throttle. Highest my iats got were 110 on about a 80 degree day, we were beating on it pretty good though.

Add some meth and crank that timing.

How do you like that size tire? Do they hook? Thinking of going with 17s but prefer them to tuck

RS/SS 4.8

Damn thats nice man. Currently thinking of going 12 to 15lbs on my truck but with street tires it might be hopeless lol.

Thanks guys. Tires hook great. Street tires at 10lbs was a handful, so I don't recommend playing on 12-15lbs with them. I know there's a bit left on the table, but it seems to run strong anyways. I will be looking for 11.4s out of it. Many people seem to give up on the 70mm to hit 10s. I think once I run meth, and make some adjustments, it just might get there. Been getting alot of rain here, so hope to run it soon.
