Default Stock gs460 dyno!

Went ahead and dynoed the car today!! Making the car stick to intended gear was a bit tricky, but managed to dyno the car in 5th gear without it downshifting after throttle is applied. Here we go.


Reason for the dyno is to have a baseline to compare with after installing the invidia exhaust system!

A little teaser

Those numbers seem kind of low.

109 degrees F and the fact that their spec is detuned to 322hp. 20% loss would have them at 257hp, so I'd say given conditions, it was better than I'd have expected.

US Spec GS460 = 342hp, Middle Eastern Spec = 322hp. 20% loss on the 322hp puts them at just under 260 which is in line with both members from the M.E. No one has received a good answer as to why theirs are detuned.

Mahmood, your A/F ratio looks fine! That's a worry for me cause based on my results, I assumed or cars were running too rich!

If indeed our cars are not, then the Apexi Neo is a waste of time for me and I might as well not risk it!
