hello, i have a boosted 420a on stock internals and the other day i went to give my buddy his first ride in my car, so i went to punch it in 1st and it cut out real bad and was sputtering. sometimes in a higher gear ill just half throttle it and it will just lag i guess you could call it. if i full throttle it in a higher gear it like wants to boost but its almost like it just sits there and thinks about it for awhile, then boosts..

Help please!!!

p.s. new to the forum
