I see in your signature you drive a GTI. I love my MK7 for daily duties.

Cant beat the GTI for its all around capability, fun car, faster than advertised and reliable.

I was going to do flexfuel for the ZLE but Im holding off for now. Before track days I just put a gallon or two of 100oct in the tank to keep things cooler. But on straight pump and basic bolt ons the increase on low end power is astounding.

Thanks for the responses all, it’s settled. I’ll wait till I do my other couple of mods.

I just want to add this. I had done Kook's 1 7/8, regular Rotofab and a TM TB. My base line with those mods was 568.09/ 544.37. After Vengeance added a 103 NW TB, 9.1 Lower and a Kong ported blower it was at 651.51/660.83. The power increase was nice but the drivability was just amazing! No more M6 bog and it felt so much better not even counting the extra power!

So even with just so bolt on mods it a tune might be worth it for some JMO.
