June 7, 2011you will see a jump in mpg with the tune so there is a plus. the higher octane when tune for it could help that even more from what i hear. what size tires you running? and gears?
June 7, 2011glad too see you went with 4.88s it will save your tranny. I told you time after time to do so and now I`m running 37s and 3.73s but I`ve got a rebuilt/upgraded tranny and have been getting 16.5mpg! lol don`t know if I want to change my gears now.
June 7, 2011shoot...you are good.let us know what you end up doing with it.
June 8, 2011IDK. so much i can do. Just want the best for the $ & that will last too
June 8, 2011got a rebuilt/upgraded tranny too. mine started to slip
June 8, 2011if i had it to spend on mine i would tune,with long tube like LPP`s or thorley tri y headers with a y pipe to a three inch single pipe. with a magnaflow or dyno bullet, then how ever you want it out the end. and ,or nice cam and torque converter but it would have to be set up for towing. between all of it you will wake up the beast with in. thats just me. for what its worth.
June 14, 2011You want power, you need cam. All the above mentioned items are complementary to a cam- you won`t see maximum output on a stock cam. I dropped about 1200 worth in my engine and got close to 105RWHP out of it. You`ll want to spend the other 1K on a new torque converter, in the 2400-2800 stall range. As long as you get a heavy duty transmission cooler, you`ll be good to go.
June 15, 2011^^^^^^this is all true., but did you see any mpg changes? just wondering.
June 15, 2011i already have heavy duty transmission cooler.
Whats a good cam??
Whats a good set of headers?
