Renntech doesn't offer a "Stage 2" tune. Curious if anyone has their regular tune with catted downpipes. And if so, do you have any data (e.g., dyno numbers, times) and what are your overall impressions? Thanks.

Hello - I’m in the early stages of ordering their HHT and from my understanding Renntech can accommodate for catted or decatted DP and also for 93 or 91 octane. Just have to let them know before hand

From my research, seems like people love Renntech and their reputation is among the best. Slightly more pricey but well worth it. This is why I’m going with Renntech!

I have the HHT stage 1 , and will be moving to Stage 2, when I get my new intercoolers etc ordered. The support, knowledge and so forth are outstanding from RennTech. Above anything, when you call, they do everything they can to answer questions etc without being a$$holes , (like some other tuners we know on here - yea EuroCharged .. you! )
