Still on base map (no revisions) so I can't really comment yet. Supposedly the tune really opens up the car around the 4th revision or so. I did experience hesitation in light acceleration once but no threw no codes and drove just fine, so I'm willing to write that one off unless it happens again. I know most people with more complete 5150 tunes swear by Jon's work, but I'm personally not at that level yet.

Some IS38 fella in the 5150 fb group reportedly ran 3mph faster going from APR 93 to 5150 E30, and ran a 11.3@123mph. I've also seen some other dyno comparisons between APR Stage 1 vs. Cobb 5150, same car, fueling, and mods, showing 5150 with less peak torque and higher horsepower, but most importantly a much smoother curve. Runs less boost than APR and is therefore less peaky. I'd guess that's smoother to drive.

Edit: Oh and also, adjustable launch control and no-lift-shift also point to Cobb. Cobb is just so feature rich...

Edit edit: nvm you're DSG

Don't want to go off topic - sorry in advance Hoon!

BUT just out of curiosity, the 12.9 @ 112mph you ran and the 12.0 @ 114mph PacDawg ran, are all times done with slicks?

I was on stock all season Hankooks deflated to 20psi, I would assume he was on slicks.

12.0 was with slicks. The higher 12s were with drag radials. Best I did with drag radials was 12.5 I think.

That's because APR is boost happy and likes to pour on the boost right away to create the high tq early on. That's why they were blowin turbos left and right. 5150 or Stratified are the "go to" tunes imo.

5150 tune has been fine for me. I did have to replace my LPFP with an aftermarket one in order to run E40 or top end would cut out but thats no fault to tune. Since you'll just be running 93 everything should be all gravy.

Awesome, thanks guys. I plan on hitting up the track this summer and will aim for similar times given I have almost the same mods as Hoon (except I'm stacked)

Hoon - Why not consider a Hybrid IS20? That way you add power and get to pretty much keep your current tune

Hoon, I would go Cobb protune/etune. The only flash is38 id consider is APR.
But id go protune 7 days out of 7. You spent lot of time and money already and to pony up more at this point, might as well do it proper.

I decided when I bought the car it would be a bolt on car, and planned accordingly...but as always I don't know when to stop.

Power is too damn addicting.
Touche my friend, touche. I literally feel like I wrote this as I just did the same thing and installed an is38.

Modding can be a slippery slope. My orignal plan for this car was jb1 and a drop in since its my commuter. But those plans didnt last long and now is38 and shopping for big turbo. Thats why I think Cobb and Eurodyne should be the tuning solutions of choice for their scalability and adjustability.

I'm afraid I'll be doing the same thing. Now that my is38 is in I want more. My only saving grace (I think) is that I have a 71 nova in my garage I'm in the process of building/restoring. But I am going to need to get maestro first or cobb,l.
