went to the track with the new setup
1.883 60ft
5.230
7.990 @ 89mph
12.56@107mph

 

take off it would start like at 5lbs and climb to 13 at shift point then go down to 7lbs and rich as hell the climb back to 13 and 11 af then drop again on the 2-3 shift why is it droping alot

 

Has it been retuned since the charger swap?
Who tuned it?

 

yea a friend of mine tuned it but the af is good wen we tuned it on the street but on the street it would lose 2 lbs at shift 2-3 with 25" tall tires at the track i use 28" slicks

 

somethings not right for sure, probably in the tune.

 

why is it in the tune of u cant control boost in the tune i bealive the af would get rich cuz of the boost drop wen it shifts

 

Marco, centrifugal doesn't build as much boost until the highest rpm's, so you're gonna see the boost drop off between gears. It should get back up to full boost near your next shift. That's another difference between the Radix and the Procharger. Also, remember that your cam is HUGE when compared to most boost cams.

 

so wat should i do ? bigger stall so the rpm wount drop that much which means less drop in boost

 

Is there any belt slip/dust in or around the pulley area?

 

A converter that is spec'd out for your exact setup will yield better results at the track. You know now better what you are looking for, since you've had the procharger at the track. Make sure you talk to them about what kind of shift extensions you are looking for. You could talk to Dave at Yank, or Chris at Circle-D, both guys are very helpful.
