2.28 60ft Spinning a little less then the 19 inch wheels but I pretty well spun for 100m
1/8th 8.56 @93.03
1/4 12.64 @ 122.53

Went quicker 60 ft and et on less boost and on 19inch tyres

Grip is the real issue.
Your 60' times are killing your 1/4 times Brule. For every tenth of a second you can reduce your 60' time, you will reduce your 1/4 time by 2 tenths. So a 1.7s 60' time would get your 1/4 times into the low 11s and your speed (122 mph) confirms that where you should be. Recently, I got a 11.47s run at 120 mph. With a powerglide and good traction, you should be able to get your 60' times down into the 1.5 - 1.6s range and times into the 10s. Some MT ET Street radials will get you there.
