Has anyone here had experience with both of these tunes and how they compare to one another? i'm running a stock 2020 is300 fsport rwd with the 2l turbocharged engine (8ar-fts). I can find more information on the d3 tune, although i live in LA and tti is local to me -- el monte, ca.

there is a lot of information on rr-racing tunes for the 3.5l v6, but fewer testimonials from those who have tuned the 8ar-fts. i plan to keep the car otherwise stock because i don't want to increase its noise, so i'm looking at stage 1 only.

side note: have tried the tom's powerbox and the jb4 and wasn't super impressed. both made the car feel kinda squirrelly, and neither addressed the turbo lag. d3 and tti claim to remap to produce boost coming sooner.

experiences appreciated.
