Its a good idea. I was looking back at past emails and realised you pointed out i didnt need a tune. Its pretty obvious i need a pulley next. With instalation of an intake does it take time for the ecu to come to terms with the intake and improve performance. I dont know if ive improved my launch but i seem to have made even more improvements from the first time i tested it. Another car length improvement. This intake has given me easily 2+ cars improvement to 90mph.
