My buddy just boght a 2005 EVO (BOO) anyway it has full exhaust turbo backand aftermarket intercooler and hard pipe kit. BUT had the stock catison the car for the moment. Heres the issue, his boost comes on late-way late-like around 4500rpm. Should the boost come on earlier like 3300? I know this is an SRT forum, just thought some one would know. Thanks

 

evo's suffer from major turbo lag. i'm not sure if it's 4500rpms late, but i know it's later than ours. tell him to check his wga out.

 

thats why we own them from a roll.....big turbo lag!!!!
