The power difference is suttle enough to where you won't feel it going from my modified SL to stock 1st gen rt/tt but driving my SL home I quickly realized 2 things.

1 The rt/tt had a much stronger clutch, I mean I nearly put my foot through the floor board when I hopped back in the SL.

2. On the same roads where the rt/tt was catapulting me and my friend to 130+ speeds with EASE, my modified SL was struggling to get just me to just over 100 in the same distance (I had spots marked off by memory).

The dohc TT suffers a bit from the emissions because getting all those cats out of the way sure does wake these things up. I mean seriously, night and day difference with just a little gutting and a DP.

FI just makes things better. FIPK on a NA 2-5 hp, FIPK on a TT is 20-30 hp, full exhaust on a NA is maybe 10 hp, full exhaust on a TT can be over 40 hp.

Seriously, FIPK, and full exhaust with the typical boost controller treatment on a healthy TT is over 300 AWHP and maxxing out the stock fuel system which maxes out just past 400 hp for reference.

You guys with NA's should do yourself a favor find one of these tt's upgrading to tdo5's and start picking up some TT parts cheap. Find a TT ecu and run wastegate pressure (6 psi), with 9b's to your hearts content. The stock tt ecu is right at home with 360 cc injectors and will keep knock away at only 6 psi.

That 6 psi from 9b's would be faster at a better price than anything you could throw at your NA. Oh well thats enough for now.
