Took my car to the Dyno last week to get a baseline. My Current Mods are:

HKS VPC
Apexi AFC2
Greddy Boost Gauge
Greggy Profec B Boost Controller
HKS Super Dragger Exhaust
3" Down Pipe
Greddy Blow Off Valve
G-Force Engineering Computer
AEM Cam Gears (Currently set at 0 for both Intake and Exhaust)



HP was 369, 372, and 375....?? Shouldn't this be a bit higher
Tq was 374, 384, and 388....??

HERE is where the problem is, there was a guy at the dyno that has a 718rwhp Supra that told me I needed to dyno it in 5th gear because it is the "True 1 to 1 Ratio" so I did and this is what happened.



As you can see if was starting to make more horspower, then it went dangerously lean, and didn't recover until 5K. Any suggenstions??? Do the HP number seem a bit Low to anyone???

Thanks i-Supra Forum for all your Help!!!

that was on pump gas? throw some 110 and put the boost at 18 pst (if your on stock twins). use the afr to fix the air fuel mixtures, its agustible by rpm. if it goes lean until 5k rpm then set the afr for more gas in the lower rpm range. the gas should fix your problem of low hp #'s

Seems low numbers for that amount of modification... did you at least try to dyno in 3rd gear? Like 94 t78 said, throw some Premium race gas in there and dyno in 3rd. Then tell me the numbers.

How much does a dyno session cost these days?

I had the same mods as you except for the downpipe on my tt94.. i was making 412rwhp and 430ft. lbs on 18psi. that was with 55k on the motor.. I think it just has to do with the tuning, make sure your bringing it to someone who knows what they are doing so they can get some extra power out of it.. and i was only running 93 octane... basically i think your problem is teh people who are tuning your car.
