This one is the car of a friend of mine, has some work on it:
- 1.6 '90
- 11:1 pistons
- Pauter rods
- HKS 264º exh. and int. cams
- MS PNP
The motor has dynoed 130 HP (9.000 rpm), and I think it's a little low for the installed mods. I attached the current msq file he's using an also a log, I don't have too much knowledge about MS so if you guys can take a look on it
Perhaps too much fuel? Needs more aggressive spark?

those numbers are low. I dunno about those hks cams though. probably needs more itbs. that said, i'm too lazy to look at the log. I run like 12.7 AFR on WOT and thats probably kinda rich, so if its any lower than that, give that a shot.
It's not 15 HP gain.
Your comparing numbers that aren't the same. The 130 is RWHP and a stock 1990 wouldn't be making much more than about 95 RWHP at best, closer to 90 RWHP. So it's more like a 40 HP gain and there probably isn't much more to be had, at best another 3-5 RWHP would be my guess.

FWIW, spanish dynamometers measure the estimated power at the flywheel. The owner of the car don't have any dyno data, the 130 hp number was given by the tuner (the tuner says he dynoed the car before the tune, he does the tune on the street).
The owner says that the car feels slower than stock, so maybe the car it's not making not even 130 hp.

Would have to see the before and after sheets. Most power I saw out of a 1.6 was just over 119 WHP - stock motor, racing beat intake, obx header, obx exhaust, and an e-manage tune. Was sort of a freak. Those cams really won't give you much power at all on a NA motor, and have you done a compression test to see how much higher your compression has actually gone?

The owner of the car only wants to know if this is caused by the MS map or not. Don't turn this into a turbo vs. n/a thread (turbo FTW!
