I took the Caddy up to a local shop called AED last weekend to do a few pulls to see what type of power it was making, & what the A/F ratio was at. After we made 1 pull, I was very shocked to see that the car was only making 382 rwhp/363 rwtq SAE, & it had a EXTREMELY lean a/f ratio of 14.8 at WOT!!!!
Needless to say, the car was tuned incorrectly by a very popular shop that shall remain nameless, so it was time for a new tune. I then called Mark Romans who is a well known local LSX tuner here in Norcal & today he tuned the car at SVS R&D in Sacramento. On their superflow dyno with Mark's new tune, the car made a best pull of 420 rwhp/393 rwtq. I am very pleased with the numbers, & not only that, but the driveability is a million times better than it previously was with the old tune.
Just as a refresher, the only engine mods are a Flowtech Cam (228/232 duration. 111 LSA, 612 intake/600 exhaust), B&B 1 3/4 Longtubes, B&B 3" catless exhaust, 30lb Ford injectors, & a drop in K&N filter.
