This is an example of a well taken care of 2003 Evo VIII making great power on 91 octane. We have been servicing this customers Evo for many years, he finally had the turbo and cams installed and then had us retune.
Mods are as follows:
IX Turbo
TBE
272 cams
1000cc injectors
GSC Beehive valvetrain
3 port BCS
ETS LICP
Muse O2Dump
Tuning Technologies 91 octane tune

363whp and 357lbft with a wide powerband, not too shabby for a 10 year old engine.
Thanks for reading
