Give me some ideas, please
Alright, I ported my intakes as some of you may know and I also converted to MAF. I also put on a BBK 70mm TB.
So anyways, I was having trouble with how my car was running...kind of poping and a little studder/bogging, checked TPS, timing, FP...all was good. Still the problem was there, changed out the 70mm back to stock, problem gone. I ran it a 100 miles or so with no issues and figure I would give the 70mm another try. I love how it runs with the 70mm, much faster, but still studders a little.
Example;
Say I take off from a dig hard, it pulls like it never has before, thur all gears with the 70mm, but when I let off the gas, and get on it easy, it will studder/bog a little untill it cleans out. Basically if I give it more gas itgets better, but just cruising it kind of like loads up.
Anyone that can enlighten me, it would be nice.

sounds like you killed the low end airvelocity in youre intake manifold when you ported it. switching to the smaller TB kinda acted like a venturi in a carb.. it spead up the air going through it wich brought youre velocity back. just a guess though.

I am still open to other options...

Another thing, it very bad when it is cold taking off, then gets better.
I also noticed I can cruse just fine, no issue untill I mat it...it will rip just fine, jet off to just cruse again and it will bog/miss for a coupe seconds till it smooths out again, then all is fine. It is mainly an issue of when I hot rod to criuse, not the other way. I have ruled out over porting, just doesn't seem to be the case. I would guess that I would see it all the time.
Anyone got any other ideas????? I need HELP
