little update: we went to swap on some new heads from another GT engine, but we noticed I had ported heads that worth good money, so we sent them at engine shop for testing, two valves were heated, they changed a spring, valve sealing probleme, well they rebuilded the heads, if we can say it this way, spring etc. im happy that the probleme is in the head and not in the bottom part of the engine, now gotta wait for them to re install everything on the car, I still need to figure out really quick If I put back my frpp hot rod cams or keep the gt oem cams, currently tuned for regular cams...i could switch back to the tune the car had when i bought it since it had the hot rods on it, but the tuner told me he got 60 rwhp with his new tune...a mustang tuner that got diffuclty tunning cammed mustang..like wtf

Fix it and call Justin at VMP Tuning. He will email you a tune (for a fee of course) but, he knows wtf he is doing. If you need confirmation check out fnsweet.com. For that matter, find a Mustang mechanic.. like we have in the states, guys that work specifically on modded stangs.

I don't know what to tell you about the cams. I don't believe hot rods are worth much power on a boosted car, if any. Hammeron should know.

I thought all that popping at start up was a valve not closing. The question is did the tuner cause the issue. I don't think i'd go back to that tuner.

Did your car ever throw a misfire code?

mighted1987

No misfire. And yes the exaust valve was not sealing corretly. But there was other problemes causing weak compression in two cylinder, You guys think i cN get a good tune even if i dont have same air ambient etc? I have couple modded things that im not aware of. Like air flow master etc. The tuner would need to know everything on my car at first.. I just spoke with the business that repaired my head, they say my engine overheated. Compression test in cylinder was say 20 in all cylinder except two that was losing and were at 6.. He say i gotta figure out what caused the heat cuz my problem could occur again

where in Canada are you?

mighted1987

Montreal sir

xkape

wow, you're way up there aren't you. I had an idea but, you being that far away, my idea is a fail.

moosestang

You all ready know why your engine over heated. The radiator was replaced once before right? It doesn't take much to over heat a motor. Driving with a leaking radiator will do it.
