On this subject what do you guys think of shift spacers? valve bodies j mods or Trans go? I figure if I'm already down there and that would be another good mod I should do it.

 

Two wheel drive or four wheel drive? The Evans according to the flex a lite website will net you 20 rwtq. If its two wheel dr then you can get a 4:30 gear ratio. I would not go any higher than that with out bigger tires.

 

4wd

 

okay so you cant do the 4:30 gears cause no one makes reverse cut gears for the front diff. Now if you don't ever plan on lifting the truck with at least 35" tires I do not recommend 4:56 gears. I would stick with 4:10's so you can still drive on the highway haha

So efans, 4:10 gears, some long tube headers with true dual exhaust, delete all the stock cats and run one magnaflow high flow cat on each bank, get a good tune from someone like Mike Troyer, and a good CAI. I like Volant's CAI with the dry core filter. Its a true CAI and use a dry type filter because it is believed that the oil from something like a K&N filter is bad for MAF's in our series trucks and engines.

Hope this helps!

 

What's cai?

 

Cold air intake

 

Oh I hav a high flow air intake from k and n 77 series with throttle body spacer

 

Throttle body spacers are nothing more than an expensive paper weight.

 

Yeah I've been hearing that a lot.. It was the first mod on the truck along with cai
