Looking for a reputable shop with an accurate Dyno in San Diego to get some HP/TQ, A/F measurements, and be able to data log.

So far I've been to 2 dynos with my G. When I was NA, I went to the Dyno Shop and pulled a 239hp with JWT PC, Ztube, Crawford Plenum, Gruppe-s y-pipe, Amuse exhaust, and TS ECU. "Heartbreaker" is an understatement. I was also running lean and pinging. This was during the SFR dyno day where almost(if not all) the modded Z's and G's pulled low numbers, Greg from Mossy pulled low numbers and prettly lean A/F in his Altima, but a stock second generation 240sx (s14) with a KA24DE pulls a 150? Strange. Maybe I should head back to this place, but pulling low numbers is kinda disheartening.

After installing the Turbonetics ST, I dyno'd at Autotech Motorsports in Chula Vista. Bad experience. Pulled 300hp/291 TQ with lean A/F(~13) ratios??!! I didn't hear any pinging during the dyno runs either. I was in a state of shock when they handed me the dyno sheet. Maybe I could believe this if I had a boost leak or if my motor was running weird. The tech sitting in the passenger seat saw boost in the 8psi range. I didn't get to data log cause they wouldn't let me in the dyno area. But according to my zeitronix during regular driving, I see boost levels at 8-9.4 psi and A/F high 10s to low 11s at WOT. Also my zeitronix reads ~-22/21.5 at vacuum, so I am doubting I have a leak. IMO this shop didn't look like the cleanest joint. Some cars seem to be just sitting and they are very low on space. They had to move four cars and still had trouble squeezing my car onto their dyno. Maybe I should have been tipped off by all the crap they had sitting on their dyno computer and around it.

I tried going to Pann but they refused since my car was too low. Guess they didn't want to break out the wood. Not very helpful or accomodating. Even Evan's tire will break out the wood to put my car on the alignment machine. Lazy...

So now I'm looking for a dyno in San Diego that will give me accurate HP/TQ and A/F measurements. I guess I'm a bit "dyno shy" at the moment. I don't want to just jump on any dyno that will take me and get strange/inaccurate numbers. Getting on the Dyno isn't free either. I searched this forum and didn't quite get what I was looking for.

Suggestions are welcome. Preferably dynos that your Zs/Gs have been on. Any feedback is welcome too. I'm new to modding cars and have been on the dyno 2 times in my life. Thanks.

 

the first time i went to the "dyno shop" in santee, before and after i installed my sc, they put me on their dynodynamics machine, and the numbers i pulled before and after the install were pretty much what i expected. "accurate" is a tough call when it comes to dynos, as the recent article in turbo mag showed. find a shop/dyno, and stick to it for before/after comparison purposes. if i were you, i'd dyno your st on the same dyno machine you used before the install, for comparison purposes.
