What setting on the TNT would get me as close to the Beta as possible, or stronger.... I don't have access to a dyno, and my butt dyno don't seem to be working too well cause it seems that no matter what I try, it doesn't seem as strong as the 4.2?

Any suggestions.

SW7 or SW9, TM-4, Timing-2, RP-1 feels the same as Beta 4.2 to me

i think its because it fuels different, where as beta fueled hard early. tnt fuels better through the whole band. IMO

The TNT doesn't touch the 4.2 on my truck w/ mods I have.

my experience with both, its seem like i can get it to about the same in the 1/8th, but i havent been able to try it on the 1/4 yet

tcr, you don't get any popping with the 4.2, do you.The 4.2 is much stronger than the standard revo, right?

highrpms

Yes, a lot stronger.

tcr

Yep, much stronger and NO popping. As I understand it the betas had a good bit of timing and I've never had any popping issues until the TNT. Even when I stacked timing on top of timing quad/smarty, I didn't have any popping. I think there's more to it then just a timing issue, the reason I think this, is because of the tranny issues I only see w/ the TNT and TNTR. I believe what we have is a TPS/ECM communicating issue that Marco will have to look into, but I sure cant explain how there are a few 03-04s that are running just fine w/ the TNT stuff.

I'm in Tom's boat, but with a 6 spd. Can't get it to not pop in 3rd no matter what setting. Bob said they will be making some fixes in October. Til then, I'm just fine with the betas.

The betas blew away the TNT on my truck, especially the low end, top end felt close but wasn't used to having to push the pedal through the floor to go fast. The betas you don't have to even push it half way and its rolling hard.

Rip, how does the regular Revo tune on #7, timing=default, RP=3, TM=3 or 4(they both run good), how does this tune run on yours, if you've tried it? My truck really likes this one when I add some pressure, it doesn't like the RP on 4 though.

Haven't messed with the revo Tom, stuck to the TNT. I din't think the revo would compare to any of the betas, am I wrong?

tcr

Yeah Rick, try it(only on #7 for some reason, #9 is no good on mine???) and let me know what you think, it's the only tune I go back and forth w/ from the 4.2. I do like it(much better than 4.11) and I will dyno it soon, I've got some new mods coming so I'll be waiting to install them first.

DUKCALN

So tcr, you like sw7, timing default huh. Is that using the stock timing basically

tcr

I do, I really do. I have no idea why 7 runs better than 9, I'm not running out of fuel on nine, it just seems sluggish. Timing on default for sure, but I don't have injectors and your 90s might like something different.

How is your milage with the 4.2 vs the revo? So did you run sw9 on the 4.2
