Did any tuner ever resolve the stepdown issue for modded tip cars ? Haven't heard anything about this in a while. I know that US tuner EVOMS had uncovered the issue, but I don't think they found a solution to the problem.

RC,
As you have a tip, I'm surprised that you haven't seen the issue in Europe. Nick described the issue which is a MAJOR problem in modding tips. I know that EVOMS was experimenting with the gas pedal and transmission/electronic brains to see if there was a reason for the power cutoff in the modded tip cars when at full throttle. I'm not a member, but 6speedonline had a couple of threads on this critical issue a while back. I'm still waiting for a solution - maybe the RUF 550 package has the issue resolved ???

Call David @ ProtoTech. There is not a step down issue with his program. I had the program in my 997TT (recently sold) and I will be putting same in my TT Cab when it arrives in October (hopefully).

Had you also raised the rev limiter or not ?!

I heard that TIP tranny gets confused if the rev limiter raised in 1-2-3-4th gears.
There isnt a problem in the 5th gear because there isnt a higher gear than 5 to get confused.

You don't seem to understand, guys: we're talking about Tiptronic ONLY and there IS a problem, simply because the Tiptronic software doesn't allow more than a certain rev figure due to "working safety" reasons. Meaning: if a Tuner raises the rev limit to 7200 rpm in the 5th gear, it doesn't help at all, the engine will still shut off power at the stock rev limiter, simply because the Tiptronic software has priority (to make sure the Tiptronic isn't "harmed"). Meaning: it is impossible to make a Tiptronic equipped Turbo faster than stock for the time being. I already know that tuners work on a modded Tiptronic software or at least on a way to try to "remove" the software switch from the motronic programming but right now, nobody seems to have a solution.
Understood? Fine.

I have tried 7000-7100 rpm rev limit and it is actually fine when you are going with %100 throttle, the problem is when you are going below 100 percent throttle. When you hit the revlimit with TP below 100% tranny puts it self in N position and you cant change any gears, you have to stop and restart the engine.
I hope i gave a little bit more explanation to the rev-limit problem.

Freak997Turbo,
The stepdown issue we are referencing is primarily for modded turbos only. The lag with our tips is generally heightened when the tip is modded. Of course, the lag is most pronounced when starting out (not torque/power braking). With modded tips there appears to be a "power cutoff" when literally flooring the cars gas petal. One solution is to simply not floor the petal and to feed the power slowly (as RC mentioned). In any event, we are really talking about fractions of a second with the lag. Truth is who wants to mod your tip with 550 plus hp (in some cases it will eventually be 700-800) only to be hamstrung with this stepdown issue ?
