Have you guys run any testing against the LET cooler. My thoughts are that if your not moving you won't gain much, and if you're waiting for the radiator fans to lower heat on the intercooler the car radiator gets alot hotter before you kick on the cooling fans around 200 plus degrees. Once moving I think they both will work fine, I'm not sure where the gain will be. This is not a dig at the product it could be the best thing since sliced bread. This is just my thoughts and they come from my Dyno tuning I had 4-5 back to back pulls inside a shop no fresh air flowing and my intake temps only hit 80* max and it was about 50* in the shop. I think with the LET cooler and the CM30 johnson pump the temps stay pretty good.
