Equates to 346 bhp from the standard 315bhp. The extra bhp must make a difference somewhere, no doubt above 3.5K but it's the torque that kicks you in the ass every time! Pound for pound, it's the best £600 I've spent! Can you post the Dyno graph? Link to comment Share on other sites More sharing options...

But prices are on the Cobb Uk site and pdk prices are more. It comes with a hand controller so not the same cost as just a remap. Mark I must've misread the site, too many options. I'll wait till something ordinary is available. Link to comment Share on other sites More sharing options...

Yes an anomaly of the 3.4 where it changes the cam I think. They worked hard trying to flatten that dip and did take over 6 hours. If you search on YouTube for Porsche 981 3.4 litres stage 1 remap by vudu garage you will get the video of them mapping my car. Link to comment Share on other sites More sharing options...
edc Posted September 1, 2018 Report Share Posted September 1, 2018 I dont think it's an anomaly as the Boxster and indeed many others types of engine have used a variation on variocam for years. Link to comment Share on other sites More sharing options...

This is true, getting rid of that dip is the main reason I started this thread. The dip is the lack of Torque I mentioned in the beginning of this post Link to comment Share on other sites More sharing options...
edc Posted September 1, 2018 Report Share Posted September 1, 2018 Different car but here's mine from my first 986 and admittedly it doesn't have the later variocam. Link to comment Share on other sites More sharing options...

It will be going for a rolling road remap once my pocket recovers from the summer holidays. But it’s now far from stock so maybe not a good comparison, more of a future aim. I haven’t got a brace, will add it to the list. Have you tried a Sprint Booster, for the money I’d give it a go - really speeds up the throttle opening. No more horses but the car certainly wakes up and race mode is fun. When you turn it off the standard car feels slow and dull. I bought one cheap on here. I bought a sprint booster for the 2.7 986 I had -no noticeable gains what so ever, don't waste your money pile of cr*p and ended up giving it away few months later to a member on here Si Link to comment Share on other sites More sharing options...

I wouldn’t say ‘gains’ as in BHP but the speed of shift and power delivery certainly. To the point that you cannot tootle around with it on the race setting or you will run up someone’s rear and when it’s off the car feels really dull. Could my mods really be making such a difference here? Even un-mapped?! Link to comment Share on other sites More sharing options...

Mark I'm not sure there is a dyno mode on the 987.2, only the 981. If there was one, I would not have been able to get my Boxster dyno'd by Charlie at Surrey Rolling Road, when we visited a while ago. Link to comment Share on other sites More sharing options...
lordlee Posted September 16, 2018 Report Share Posted September 16, 2018 I spoke to Wayne Schofield at ChipWizards and he told me there’s absolutely no point in mapping the 3.4 non DFI engine. As he’s a well respected tuner I took his advice and left well alone. Link to comment Share on other sites More sharing options...
