Been trying to decide on the 93 vs e85 but these numbers pretty much have me sold on the e85. I have seen some people say you need injectors and others say there is no need, anyone know which is correct?

No need for injectors. I think Lund even states now, no need for injectors with a GT350IM.

Injectors are cheap and easy to do when you swap IM. Better safe than sorry.

Look at that ET and MPH in your sig :eyebulge:

What wheel/tire setup are you running? How are you launching your car? What DA was that run in?

Everyone needs to pool money and get you on a dyno, trapping 124 you have to be making over 500whp

Don't see those mods making more than 460-470whp. Very impressive time and mph either way!

I know, that's why I want to see a dyno... I haven't seen any other n/a bolt on S550s trap 124. I have seen plenty dyno 460-470, but none are trapping 124 with similar mods. Driver mod only goes so far for traps.
