b4194t2 tuning for 300hp?
 

hi guys

think we sorted the running issues now so would like to find out what to do about tuning my t4 to around the 300hp mark? alot of people been saying its hard so if anyone can help it would be much appreciated. if is hard is there no reason i can install a AFR gauge and adjust boost and fuel to make my power or is this not appropriate with these engines?
also i think the car has had a remap already as there is a dyno print out with it running 250hp at flywheel and 223 at wheels :/

any help would be appreciated

cheers guys
