I'm interested in getting the epic stage 1 tune, but I'd love to hear people reviews specifically on the stage 1 tune.

Good question. I have only ever sold the race tune, and run it personally on the E92 since I started tracking it, which was instantly.

Car has never skipped a beat and I've converted many friends over and they've all been stoked with the better power and drivability.

My car makes 400whp on 91 octane and feels incredible up to 8500rpm.
Send me a PM if you want some help getting it all sorted and choosing the right combination of parts.

400whp on 91 octane? doesnt sound accurate, sorry.

He didn't mention mods, it's possible, esp on the optimistic eas dyno.

It's possible, I got 402 on 93 octane with Randy's EPIC tune and pretty much every bolt on you can think of, including the BW catless forward facing xpipe. The 383 number was without the xpipe, instead was test pipes and the Alpine tune.

I plan on switching from Alpine to EPIC ... I'm curious and what the differences are. Where do you notice the changes between the tune?

Yes, 91 octane. Here's the graph during tuning as we played around with hardware configurations. (x-pipes, intake, tune)

Sounds accurate. I made 405whp (+300wtq) on the same shitty 91 octane (ARCO, SoCal’s cheapest)…Epic tune, Bimmerworld headers+mid-pipe, MS pulleys+intake. Some people claim Dyno Jet reads high, sure. What’s more valuable is how this number compares to other cars on the same dyno. The only thing evident is, Epic is king, and people don’t give BimmerWorld headers enough credit.

That mid-range torque with the headers is nuts! +3hp/+15 lb-ft compared to mine.

And yes, I love when people say things like "sorry, that doesn't sound accurate."

Im reviving this as i just bought a car with a Bimmerworld xpipe pipe with modified oem muffler. I have an ESS xpipe and Meistershaft GTC laying off to the side... wondering if Epic is the move.

My previous car made 374hp with Alpine ESS/MEISTERSHAFT/Dinan intake/MS pullies. This car also has Alpine and thinking of trying something new (no issues, just wondering).

My car’s been tuned with Epic for ~20k miles, runs flawlessly. I’ve got track days mixed in too. The best testiment to reliability is I’ve never had to contact Randy in my period of being tuned, other than when I bought it.
My car has a Bimmerworld x-pipe, corsa mufflers, full Eventuri intake/plenum.

Amazing, thank you!

We basically have the set up (I also have an Eventuri plenum). What are your duno numbers? Did you get a tranny tune from him as well? I hear there are multiple GTS and Euro tunes, does he give them all to ya?

I haven’t dyno’d my car yet, but it’s a night and day difference especially at 8600 rpm and with how the torque curve is moved. I don’t have pulleys so I’m probably not at the top end of the power range. But I am full catless with 92 octane, I know Sub 2 speed house’s car is at 400 whp with 91(?).

I have the GTS DCT tune as well. I’m not sure what version it is, but it’s extremely responsive. Brings the shift feel to 95%+/- of PDK.

Building a sleeved high compression 4.1L S65 right now. After talking with the builder I am using Randy at Epic. Already had a conversation and lucky for me I don't need to tune it while I am doing my brake in. Once I get it done I'll be on the Dyno with Randy remote tuning it. Hope to be tuning early March'26.
