    First impressions of the TD NA upgrade (EL manifold, filter and ECU remap) and MTEC shifter spring and bush. Love it! Things I immediately noticed - Slightly more aggressive and louder engine note, not much, but nicely so. (I didn’t go for a catback exhaust) Now extra power between 3-5k revs and linear power delivery, no torque dip, meaning in 2nd and 3rd gear acceleration out of corners much less pedal (probably 50% less) is required to reach the same speeds on the road. The extra acceleration in this range and the more predictable power delivery will be so useful on trackdays. Gear shifter slightly stiffer and stronger to centre into neutral. Worth doing during the NA upgrade but I was fairly happy with the gear shift before, although if going back would feel a bit ‘loose’ I guess. Gearbox noise/whine a little louder in lower gears, but quite subtle. Minor drawbacks - Slightly louder cabin noise, since motorway speeds in 6th tend to keep the revs in that 3-5k band. It wasn’t exactly quiet before though so no issues here. Top end of revs no longer feel as punchy just relative to the mid range. Overall there is objectively more power at the top but maybe now outshined by the mid range it’s not quite as noticeable. I think I just need to readjust to the more linear feel in general and it’ll be fine. Im expecting fuel efficiency to dip a bit since I do mostly motorway driving daily but that’s not why we buy these cars! Here’s the dyno data: Apparently my car already started with decent power so the gains were less. But it’s the loss of the 3-5k torque dip that has made the most difference. Now officially 200hp is also nice! Big thanks to @Mike@TD.co.uk and team at TD!!

    Glad to hear you are pleased with it. I found mine to be similar on fuel to before. I retained the original exhaust too and actually quite like the sound and good to know it is safe for DB levels at all tracks. Only thing I may not do if I had hindsight would be the gearbox mount upgrade as its not that much of a difference in my opinion and not worth the extra vibrations and noise. Shifter springs I do like though, if you drive a stock car it makes that one feel very slack.
