My car is slow 6.7 0-60 and 15.00 1/4mi

The ObX exhaust is the second aftermarket exhaust and I could tell its made very well and its straight through design I don't think it could slow the car down at all.
Also throttle body spacer Is the one that DAve O was advertising that there was gains on it, I don't see how it could slow the car down.
Fan Delete mod is for the Clutch fan, I replaced it with dual electrical units just like all newer Gs have.
Spacer is my prime suspect right now, either there is a slight vacuum leak somewhere or spacers just slow the car down in general. I thought my skunk2 that i had on before slowed the car down a tenth or so, maybe motordyne has a similar effect.

After you do all of this find the ECU quick reset on one of the threads (search). Do that and then turn the car on and let it sit and idle for about 10 minutes and then take it out for a spirited run. I would also look into some type of air intake.

I got SAFC installed but have not tunned it yet,
I had already tried putting factory muffler back on and there is no increase in performance at all and it sounds like crap compared to what i have on now...
I sopose I can try and take of throttle spacer but I seriously doubt it has any effect either way.
I do ECU reset I do all the time when I change something
I don,t know what the problem is, maybe my engine is wearing out and I'm loosing compression or something like that,,,I have no clue

What after market air intake did you have?

OP... I have the TBS (among other things)... and run 14.1 trapping 101 mph on a track that is 1500 feet above sea level in high 80-degree weather... I consistently get 2.1 60' and that's with crappy street tire launching off idle (in an AT).
You do not need to take the TBS off (I have the same one you do)... the exhaust might be a bad choice... what I highly suggest you do is get a dyno tune with air fuel ratio... if you are running lean all your mods are working and you just need a tune (like Osiris or Technosquare).

Then save up 500 a buy and used greddy exhaust or something decent and then put it on. Take it back and have it retuned and see what happens. I bet you will be putting down some nice numbers.
This is the best advice imo.
