My track results show a combined +0.365 ET 4.58 MPH 4000lbs = gain of about 45 HP. - minus better weather, -5-10hp No tune (mine was, in the end, just KR reduction timing changes) So, 35-40rwhp? (Absolute low end = +30rwhp.) What do LT's, bolt-on only, high-flow cats, with no tune claim for RWHP? Where's that duck smiley? Hehehe. Padre |

That's Awsome. Why does everyone frown on Shorties then? Is your gulp possibly what I mentioned above?

Again, thanks for posting all the detail mod by mod. With respect to trap speed, I might not be taking into account the raceweight and the overall gearing of the car. Do you finish the quarter in 3rd or 4th? What's next a small gear change?

If I put mine in sport mode it doesn't do the "gulp" but it doesn't shift as hard as in drive. I wonder if I can swap this around in the ECM?

Awesome thread Padre, been following each up grade and trying to keep up on the upgrades. Can’t decide if I want to go high flows next or gears, any thoughts? I don’t have any tune and trying not to use one until later down the road. Thanks a bunch for sharing.

They are related somehow, because I did not lift on the throttle, but the reported TPS dropped from 84% (what the computer sees as wide open), to the 40%'s or somesuch. So something in the computer backed you off the throttle like traction control does. But I had traction control off, so the exact cause of the "gulp" is unknown to me. But the fix, for me, was to add more time (back in) to the desired shift time. Just a gut feeling, and it worked.

So I have a 3.45 differential from an M6 and it goes in this week (hoping). A6 differential is 3.27. That ought to stretch out the time in 4th, moving earlier the 3-4 upshift. I haven't done the math yet, but I know I'll be happy with an earlier shift. Anybody want a slightly used A6 3.27 diff? It actually would be great for a 3.73 gear swap from a vendor like Jannetty, and then you could sell your old diff... Padre |

I think the JBA Midpipes are a great mod for keeping most of the stock sound and not making the AFM noise worse, as headers do. It's an easy +20hp and easy to install. Gears are also a great mod for performance and keeping the daily driving good. Torque Converter is great for performance but hurts daily driving (revving higher off the line and therefore noisier).

I'm losing my mind, for some reason I though you had gone 12.19@111mph and actually you went 112.89mph... Practically 113mph with bolt-ons is fantastic and just about 4000 raceweight to boot.
How much trial and error has it taken you to figure out the trans tuning with HPT?

The tranny tune with HP Tuners was done after a lot of research on their forums and elsewhere. But it boiled down to simple changes in the pressure and desired shift times. I changed it only in shifts 1-2, 2-3, and 3-4 since that's all I need at the track, and around town I put the stock tranny tune back in. Actual adjustment at the track took just a few runs and one tweak (when I had the gulp). Padre |
