1. my MAP ef2.5 exceeded my expectations. i didn't expect it to spool as quickly as it does, pack the punch it does, or make the power it does (given my other mods). it was supposed to be a "hold me over" turbo until i could score an FP Red BB. i don't think i'll be getting rid of the MAP until it dies. it's amazing.
2. rebuilding my rear diff. the car exits corners 200% different than it used to. who knew such a quick and easy adjustment would work so well? wow.
3. coilovers or rake adjustment. i installed V3s and set my rake to approx 5mm higher in the rear. i'm not sure which helped as i did them at the same time.. but my car is now VERY neutral. with my Bilsteins/H&R springs, the car pushed like no other. i learned about rake, fixed it, and now the car drives brilliantly through turns.

 

what are your plugs gapped at? i had the Spoolin' COP and the car seemed to run worse. i swapped the stock ignition on and it ran better. i've never looked back. well.. that and i make less than 400whp right now, so i don't quite feel a need.

 

a dyno tune... after a year of saving up and purchasing and installing bolt on parts... nothing beats a dyno tune.... made so much difference....

went from a 8 to 9 turbo, full tbe, injen ic kit/intake, ebay 3.5" ic, spoolinup cop, fftec boost pill, kelford cams, supertech valve springs/ti retainers, walbro 255, fic 1050

made 317whp/326wtq on 91 pump 24psi tapering to 21 mustang dyno

 

2.4LR with 6766 turbo and the Varex muffler I just installed. Open exhaust when open, nice and quiet when closed with a push of a button.

 

Shifter bushings, or a tune.

 

the 24.99 or whatever it is for Evoscan. EcuFlash is free but those together are the best mods. They have helped me pick up the most horsepower and since my school has a AWD mustang dyno i run it on the dyno almost every week.

 

ACD flash, Robispec springs, TRE 12-plate, ER SD tune, Sparktech COP ... and others. But these stand out.

 

Shifter bushings were definitely the biggest bang for the buck. My MAP downpipe and ETS LICP exceeded my expectations.

 

flossy griprod, ohlins dfv r/t are my 2 favs.

 

Aquamist hfs3, perrin intake n filter

 

Torque solution rear engine mount made shifting feel so much smoother, and also any power mods is always a plus.

 

aem ems v2

 

had room for an extra 3 in pipe from air filter to bottom of the front left bumper, decided to throw in a aluminum pipe for extra cold air leading into my filter.

 

All my Cusco parts:

*6-point roll cage
*All available chassis bars/braces
*Front Sway bar

I love how tight the car feels and handles...

 

Worth it even for those that have shifter bushings and underhood shifter cable bushings?


Tune was my favorite mod
