Got my car back from the shop a couple days ago and I wanted to get some feedback on my results. Based off others results I was expecting higher numbers than this but the car feels pretty strong so I'm happy.
Car is 2014 a6 with the following mods
-TSP 1 7/8 LTH w/o cats
-Soler ported tb
-Holley CAI
-E85
-Dyno tune
Tuner said the car was tuned on E60 and to expect slightly better numbers once it gets full E85 on it.
Take a look and Lmk what you guys think. I'm a rookie with reading dyno sheets so a breakdown, or any input is appreciated!
Personally, I would think that you get more than that but I haven't been through the process yet. I have a stock car and am getting ready to have a tune and CAI installed this week. I will chime back in.
Any issues with the TSP headers? I hear they have fitment issues or rattling sometimes. Trying to decide on TSP vs Kooks right now since the TSP are at least 600 less.

They fit really good. The passenger side header was a little tight but I got it no problem. Maybe had 2 fingers space on that side. And I didn't have to remove the mufflers, just pushed em back as far as they could go. I'd buy them again without hesitation.
My 16 C7 made 444 with the mods in my sig. I have just added a ported TB and IM but haven't had it back on the dyno yet but will this Wednesday. Mine made 429 on E85 and tune. Added long tubes and xpipe, I never base what shows up on the dyno to what really shows up at the drag strip. CAIs usually don't add much rwhp on the dyno either. I still have the stock air box on mine with a new filter.

I think that seems about right, what were your expectations? If you had full E85 in there you'd see another 5-10 rwhp probably. Run it to empty, fill it with E85 and see if your tuner will throw it back on the dyno for you just to check it out.
any other comments? im thinking of talking to the tuner and seeing what he has to say
Take it to the drags (test 'n tune) and compare the best time/mph to what's on the fast list before you deal with the tuner. Dyno numbers are meaningless without real world results. I got a best of 3 pulls at 394 HP and then ran a 10.80 @ 126.84 (C6 bolt-on).
I had mine tuned two weeks ago. I have a 19 GS automatic. Ported TB, CIA, x pipe. My car was running rough. It was my first tune on a Vette. It ended up with 407 rwhp. But, it’s still legal in California. I know, everything I have is illegal. It seams to be less h/p than others in this thread but it runs so well. The tongue was more than the h/p. It pulls hard. While he was in there, he turned off the 8 to 4 cylinders thing. I have a Range for sale. Lol. The tuner charged me $1,000.00 cash. Did I pay too much? It was worth it.
