I want to get your input with this. I have a Whipple and at the time I ordered it I had the option of doing the Accufab TB and opt'd not too ($500). After thinking it over I changed my mind called up Whipple and they said you could "modify/cut" on the intake plentum to accomodate the Accufab. Well long story short we matched up the TB and there was no way it was going to work. Will it be worth my while getting the correct plentum and Accufab in reference to gains? I dont want to go thru doing this if Im going see maybe +5-10hp. Same thing goes for the MAF I have a stock MAF with the Mafia. Go with bigger or no?....I know that BBK makes a twin 65mm but I am not too happy with BBK.
