It has a few mods done, Full twin 2.5" exhaust, Fuel pump, Front mount (stock piping though), intake, injectors, valve springs. It had a dyno sheet done by herrod motorsports showing 270 rwkw at 14psi. Is this abit low for the mods? or could the standard intercooler piping be holding it back?

That boost does seem to high.

Replacement Nizpro cold side pipes/cooler, 42lb inj, Manta full 2x2.5" (3.5" split dump) and intank GSS294. Stock turbo/actuator. Pretty flat boost curve:The stock crossover isn't so much the problem as the length of the associated pipe work causing lag from what I understand. Also remember auto vs manual, autos show a bit less. Don't even mention the dyno...The freer flowing the air pathway the less boost required. Get a short intake-cooler-throttle body pathway, a nice plenum and big exhaust and you don't need to jam as much boost in. Costs more though Edited 28/08/11 11:40 AM by -SteveR-

Seen plenty 270/290rwk cars beat 300+ cars. As long as it is tuned right that's the main thing. They don't have a happy dyno like some tuners out there.

jaysevu Member 27 Member For: 15y 2m 9d Posted 29/08/11 12:15 AM Author Posted 29/08/11 12:15 AM Yeah I'd think coming from herrod it would be a decent tune. The cars manual and 65000k's
