We really need an official thread on this site to discuss both stage 1 and stage 2 tunes from JHM. Ask any questions and share your experiences here as well. We have a number of members, including myself, who have stage 1 and stage 2. I’ve talked (gushed) about it endlessly so it’d be great if others chimed in. I’ll go back and find my initial impressions for both and post it here along with dyno runs and what not.
If the RS5 had come like this from the factory, it’d be legendary and leagues above its counterparts from BMW and MB during the same time period.
Here are my initial impressions after flashing to stage 1, made on 8/24/18 and I’m trying to be conservative in my thoughts and not be too enthusiastic with new mod bias ; " So my initial impression is very positive with the tune. I’ll simply describe the car as “crisp” and more authoritative with a better upper midrange and top end pull.
-My first cold start was a bit rough, I’ll admit, but the cacophony seemed to die down more quickly. Smelled a bit richer.
-I did take it to redline and the car felt faster. I’m going to hold off final judgement as it was ten degrees cooler this morning than when I usually head into work at noon. (83F to 93F). But it does seem to pull harder, even though the midrange. I’ll be 100 degrees when I head home so we’ll see if I feel the same way, LOL.
-The throttle feels snappier overall but not in a throttle hijack sort of way. The easy modulation factor is still there and initial throttle tip in isn’t overly aggressive but it does seem to accelerate more quickly.
-Downshift blips feel smoother and more accurate
-I drove around in Drive at times and it would downshift into 6th from 7th more readily.
-I think I noticed one abrupt transition from neutral or zero throttle to WOT in third, around 4K rpm. And I “think” I have that logged. Can send to you Jake if you’d like me to. Wasn’t bad but I did notice it and didn’t have a chance to repeat.
The car does seem to be a bit smoother, more crisp and pull more readily through the RPM range. Enough so that I actually have no doubt it makes more power over the OEM coding.
I’m scheduled to dyno again next Thursday, that’s the soonest he can get me in. He’s off today through Monday (birthday) so I won’t have the dynojet files until Monday, sigh. But I’m off that day and will be able to plot them all out and post them up."
