I ran my car on a chassis dyno today and I can't believe how rich it was at WOT. I only have a K&N air filter with the stock air box opened up and a throttle body bypass , but at WOT my AFR was as high as 9.8:1! I have a Halltech T1 intake and 30# injectors on the way , so I'm sure that I will need the MAFT. Hell , based on my AFR today , I think I would be able to pick up 15 rwhp with just a MAFT. In case you want to know , my car made 348 hp and 348 ft/lbs at the rear wheels. I'll be sure to let everyone know what kind of numbers it puts up after the intake , injectors and MAFT. Thanks in advance.
