I would highly recommend this intercooler over stock.
It definatley woke up my car and I can say with some accuracy that I gained about 3 mph in the 1/8th over the stock IC.
My combo is a TA60, 57lb injectors, Extender/Trans +/LT1 MAF and progressive Alky kit along with the usual stuff.
The intercooler seemed to help airflow and the turbo didn't have to work as hard. This IC also allowed me to see 25-26 psi and my car went 89 mph first time out the the same settings as I had with my stock IC.
After a few weeks of tuning, I can consistently see 90-91 mph at this track.
In the 1/4 I don't have any comparison data as my combo had changed since my last visit. But my best 1/4 mph performance with the combo has been 11.8 @ 116 and I would say the intercooler played a large part in getting me there........as an aside, at the 1/4 mile track I can see 93-94 mph in the 1/8th.
