Boost hits too hard. Should I solve it with a bigger turbo?

So I really love my setup for the most part. See sig below. The te-44 hits hard like a big block. It is really fun on the street from a roll, but from a dig or anything under 40 I completely blow the tires off. It used to be much worse, but dr's and baseline suspensions UCA's improved that drastically. I built my setup for a bigger turbo, but am really enjoying the big block feel my 44 gives me. That being said, would I be happier with something like a te-62?
 
I went from a 49 to a 61 and didnt notice any difference....Track times were close too. I would buy a used billet turbo.
 
Looks like your set up would be perfect for a Garrett .63 A/R 6262 journal bearing turbo?
Suggest you contact bison & see what he'd recommend & build for you.

Or, if you wanna keep your TE-44, then try going to a lower stalled converter…..3200 is way too much for a TE-44 IMHO. It's gonna blow the tires off with this set up.
Most go with a 2800 stall for a journal bearing TE-44.

Spinning your tires looks really cool...and is also the quickest way to getting your ass handed to you in a race. That convertor is too loose for that turbo. A 6262 JB is a good match for that convertor with a set of heads that have been opened up. I have an AC 16930 convertor that stalls around 3000 to 3200 with a CEA 6262 JB with a set of heads that can breathe. Time is in my sig.
 
Most people would love to have your problem... I also think used JB 6263.... I went from a old style TA66 to a 6466 and some other big Mods and it makes a huge difference.. But Brian is the guy like they said.. Good luck
 
You could try to modulate the boost with your right foot a bit. My 44 hits hard too, so I just don't full throttle it from a standing start. I would think a big block car would act the same and that's how they did it back in the day. I've never heard of trying to slow down spool by going tighter unless the TC isn't coupling, but it doesn't sound like yours is that loose.
 
If you go with a front mount IC, the larger IC and piping will solve your problem and you should pick up on the top end.

I always wondered if a FM would make a difference. It makes sense the extra area would take longer to pressurize, but I've also read that the air in the system flows like a river when engine is running and whole system just comes up on pressure the same.
 
I doubt the converter is a true 3200. It is most likely a 0 pump, which is around 2800. I have used 0 pumps with stock engines with TE44's running low 11's to stroked 109's with 76GTQ's running 9's. I never had traction issues with a TE44 and a Vigilante 0 pump with MT drag radials. What tires are you running?

If you double the volume it will take double the time to pressurize it. It's not exactly linear as the wastegate won't crack as soon with the greatly enhanced square footage it has to pressurize.
 
What about progressive boost controller?
You can start at low boost then raise the psi after rpms

With the stock IC I ran I used to blow off my tires in going sideways fashion, after the front mount it helped widen the powerband.
 
what you need is some way to cut the boost down based on throttle position, that way you can truely modulate the power with you foot. If the turbo is hitting hard, then you are likely having a hard time holding the turbo back with your foot.

what sort of boost are you running on the street, and what is your wastegate setup?

Tuner style with no other goodies might give you a soft enough ramp speed to speed the car up and make it more streetable.
 
What about throwing a .85 housing on the turbo?
