Hemifevertuning.com using Diablosport Trinity

Oh my god, is all I can say. I was fairly happy with my 87 tune I installed using my Diablosport Trinity, but then I found out about a company called hemifevertuning.com and how Sean Powell provides a custom tune utilizing your Trinity or Intune. He offers either an 89 or 93 tune.

I installed the 89 tune and it's night and day when comparing the stock Diable 87 performance tune to Hemifever's 89 tune. The most noticeable difference is that Sean actually reprograms the TCM. Now I have zero hesitation when stepping on the gas. He'll also have you send a data log so he can makes final tweeks to the tune to get the optimum performance out of it and yes, he adjusts for those that have bolt on's such as my Mopar CAI!

The great news, is that this only cost $125 if you want to download it to your Diablosport Tuner or if you don't have one, he is a Diablo Dealer and offers a discount with his tunes already installed. It's the best $125 I have spent!

Re: Hemifevertuning.com using Diablosport Trinity

I've only heard very positive reviews on his tunes. If you buy the Trinity form him, his custom tunes are free! I don't know why one would buy from anywhere else...I hope to get one for my Ram within a year.

Re: Hemifevertuning.com using Diablosport Trinity

I already had my Trinity that I used on my 05 5.7 GC, so it was money well spent. It is night and day compared to the canned tune you get from Diablo. Throttle response is greatly improved and shifts are snappy and quick. You can't beat his customer service either. It's a no-brainer.

Re: Hemifevertuning.com using Diablosport Trinity

hmmm...very tempting and although this read like an ad, i've heard and seen nothing but good things. I may bite the bullet on this although i'm not satisfied with the shortcomings/bugs of the intune itself.

Re: Hemifevertuning.com using Diablosport Trinity

+rep, thanks dizz. I've delayed doing a tuner to now, that's over. Really looking forward to getting rid of the ETC lag.

That's the biggest complement you can pay. All that is advertised on his website is the truth. I had the regular Diablo 87 performance tune installed and had it for about 3 months and I can tell you it is night and day with his tune. What's also great is that he wants you to send him the data log and he will tweak the tune specific to your vehicle.

Re: Hemifevertuning.com using Diablosport Trinity

Same experience here with my local NYC tuner. The canned tunes are great but the custom tune is where the hemi really shines. No lag, snappy and quicker shifts and overall a great driving experience. A custom tune should be on everyones list of mandatory mods. I picked up 60bhp with custom tune, CAI ported 85mm TB and corsa catback.

As long as the trinity is not married to another vehicle yet you can. You tune the vehicle with one of the Diablo Tunes, either 87 or 93 octane and email Sean both the original factory tune and the diablo tune for your vehicle. He then sends back a tune via email and you download it to your trinity then to you jeep. It's not hard to do at all.

Trinity can only be mated to one VIN or vehicle. One it is unmarried it can be sold or used on another vehicle.
